Betta Spawn Log : BSL20180328 : HMPK Koi (M) x HMPK Koi (S)

Longest possible pair that we've conditioned before breeding, roughly 1-plus month. SO was not hurried to breed this pair and wanted to wait for other spawn to mature enough. Nevertheless, we've noticed that the female Betta have been ready for so long and might as well let both mate and breed.

Male: HMPK Koi
Age: 3+ months
Temperaments: Active and curious.
Size: Small (3.5cm body only)
Grade: B

Always curious and not afraid to confront us when ever we feed the male Betta. This is one male Betta which swims in an aggressive and majestic way.



Female: HMPK Koi
Age: 3+ months
Temperaments: Curious.
Size: Small (3.0cm body only)
Grade: B

Nothing particular special about this female Betta. Just quite quiet.


Log Notes
2018-03-28
The female Betta was let out from the isolation cup and both Bettas started to mate without much trouble. However, we've noticed not much eggs were produced and kind of disappointed with the outcome. We decided to let both fishes to settle down during the night.

2018-03-29
The male started to chase the female Betta. We assumed that the mating should have been completed. Unfortunately, we don't see much eggs in the bubble nest. The female Betta was jarred and quarantined. The female was looking quite good without any damages to its fins. Most likely explanation was both Bettas was conditioned within the breeding tank for so long. Maybe that could be the reason why not much eggs was fertilized during mating?

2018-04-06
Not many fry found within the tank as most were swimming or hiding at the back of the breeding tank covered by thick aquarium tank.

2018-04-10
No fry left.

Introspection
1/ We've underestimated the stress level of certain male Betta. Some male Bettas were not comfortable with human presence and may led them to eat up all the fry.

Betta Spawn Log : BSL20180327 : HM Blue (M) x HMPK Koi (S)

Yes, the continuity of BSL20180305, same pair of Betta fishes and same environment. Both the Bettas were healthy and especially the female, which was full of eggs. Our plan this time was to remove the male Betta once the fry starts to swimming freely (or horizontally).

Log Notes
2018-03-26
The female Betta was full of eggs and was swimming slowly in the sorority tank. We've decided to get it out to the same breeding tank.

2018-03-27
We didn't realize but the female Betta was dropping eggs on its own and piled it up in the plastic bottle in the breeding tank. Immediately we released it out so it can mate with the male. The male Betta have been busy making the bubble nest. Upon released, both already starting to mate but the female Betta was dropping eggs non-stop (see photo below), even without mating. We suspected that too many eggs within the female itself. Again, pity that we've so many unfertilized eggs. We should have released it and let it mate immediately before we headed up to work this morning. Let's us how this goes!


2018-03-28
The female Betta was removed from the breeding tank. There were some eggs in the bubble nest and the male Betta was making more bubbles to make it stronger.

2018-03-20
Nope. Again, no eggs were found in the bubble nest or what the remains of it. We're going to give up breeding this HM. Might as well give the HM a good rest and keep it as it.

2018-05-20
Cleaned up the breeding tank and moved the male Betta into a smaller plastic jar.

Introspection
1/ Numerous attempts have been tried with this male Betta. It seemed the effort was fruitless as the male Betta was easily spooked and it was eating up all the fry.

Betta Spawn Log : BSL20180326 : HMPK Blue + Red (M) x HMPK Blue (S)

Probably the longest breeding process for this male Betta. We wish to breed more Betta which have this body shape but different colours. Maybe this will come after a few generations.

Male: HMPK Blue + Red
Age: 3+ months
Temperaments: Extremely aggressive and brave.
Size: Medium (3.5cm body only)
Grade: B

If not for the colour and under-developed fins, this male Betta have the best overall body shape in our collection. It's not afraid of us and always flared at us. We've seen how it tore apart several female Bettas fins and causing trauma to these females. One of the female Betta, which was purchased as a pair, was so frightened to be put along side this male Betta.


Female: HMPK Red Blue
Age: 3+ months
Temperaments: Passive.
Size: Small (2.5cm body only)
Grade: C

Generally passive and not much eggs produced. We've chosen this one as we want to breed blue colour HMPK. Nevertheless, this female have successfully mated with the male (finally)!


Log Notes
2018-03-26
Found some eggs in the bubble nest, not a lot and scattered around. Immediately removed both female Bettas as the this male Betta was very aggressive and biting all the females. We've tried to add more female Bettas to encourage competition among the female Bettas so that it can breed with this male. We definitely need to revise our preparation procedures.



2018-03-27
Found some fry were swimming vertically and the male Betta was busy picking it up. We also noticed that the male Betta was too tired and not flaring anymore but resting at the bottom of the breeding tank. A common behaviour of overly aggressive male Betta after post-breeding.

2018-04-17
Moved the breeding tank to different rack. Still quite a large number of fry and the male Betta was not as aggressive as before.

2018-05-20
Cleaned up the breeding tank. Remaining fry (8 found) were moved to BSL20180316. There fry were too small and not growing at usual rate.

Introspection
1/ Monitor the fry growth rate. Big breeding tank may not be suitable if the number of fry were too small.

This Week I Learned 2018 - Week 12

Last week post or something from the past.

A minor adjustment of book placement and I've been reading one page per day without any interruption for the whole week. Keep the reading streak going!

“城市套路深,我要回农村”。曾经流行过的网络流行语。最近开始关注中文网络的动向,也接触不少网络流行语。话说回来,是人性本善,还是人性本恶?或是性无善恶?姜源的解说,读起来蛮有道理的。

There is a Chinese idiom, “对症下药”. With the right medication, a disease can be effectively cured. Surprisingly the medication that I've impulsively bought reduce the inflammation and speed up the recovery process. The problem have been plagued me for the past 4 years and it's finally reaching to an end. Surprising (not really after you went through different doctors), I've consulted a few doctors in the past but they can't seem to give the right prescriptions (can't blame them, doctor these days just want to sell more medications that fix symptoms). In the end, I've to thank to that pharmacist who ever he is.

Two interesting English words I've found, may sounds a bit too fancy. Big word, they said, nevertheless sounds "intelligence". Affordance. When come to daily object interaction, the handle of a cup is a good example to describe the words. The handle gives an obvious way on holding it. Kerfuffle. This was a popular words this week in the NBA, basically refers to a commotion between NBA players. Yes, big word.

Back to regular weekly learning new English words. Here we go.
The posthumous (作者死后出版的) publication of the researcher on the hydrodynamic (水力的) model of the eruption of the underwater volcano aroused quite a few interests among the archaeology field. While the late researcher main focus of the publication was on the igneous (火成岩) rocks formation, there was a section which documented about the ancient ideograph (象形文字) found within the underground caves carved (雕刻) by the lava near the coastal(沿海) and insular (海岛的) area. Insulated (使隔离) from the air under the sea, archaeologists are still puzzled how the ancient civilization were once ever existed in that area.
Hoarding? Too much stuff? Read this post on how a Redditor removed that habit. In short, go to thrift shop on weekly basis, you will aware that most stuff bought or collected will ended up there. The most memorable things are your experience in life, captured in photos or some ways or another. Definitely something to ponder.

Betta Spawn Log : BSL20180325 : HMPK Marble Blue (S) x HMPK Red (S)

We made so many mistakes with this spawn and learned quite a lot of hard lessons here. The main lesson here was, never put in a pair of Betta fishes with mismatch size, especially when the male was smaller than the female.

Male: HMPK Marble Blue
Age: 3+ months
Temperaments: Extremely aggressive and brave.
Size: Small (3.0cm body only)
Grade: B

The last surviving Marble we have. Initially we thought it won't breed because it doesn't seem to make any bubbles since the first day we have it. And, certain Betta fishes from our northern neighboring country may be sterilized before being shipped out to us. But after certain arousal medication, it started to make bubble and afterward, bubble nest.


Female: HMPK Red Base
Age: 3+ months
Temperaments: Aggresive.
Size: Small (3.0cm body only)
Grade: C

Quite aggressive for its size and kept flaring at other male Bettas.


Log Notes
2018-03-25
Both male and femala Betta was flaring each other and mating was tedious and aggressive. Both did mate, but only once or twice. No eggs were seen in the bubble nest.

We've noticed that the male Betta was injured and was panting in the far corner resting on the plastic bottle. Its operculum (the area that protect the gills) was shredded (See the arrow in the photo below). We immediately removed it from the breeding tank and quarantined it. As we're out of Indian Almond leaves, we resorted to use Malachite Green and keep the water level as low as possible. The recovery jar was put within a box so the male will not be interrupted.


2018-03-26
The male Betta was doing well but still very weak. I've changed 80% water changed but retain the Machinate Green water. We will switch to different medication tomorrow if we still can't find any Indian Almond leaves.

Meanwhile, the female Betta was shredding eggs and picked it up itself. This was the first time we observed that a female Betta was shredding its own eggs if it can't find a male Betta to mate. Pity though, quite a number of eggs were wasted.

2018-03-27
The male Betta was looking better and more active today. I believe its recovery was doing well.

Retrospection
1/ Size does matter! If you want to breed Betta fish, make sure you buy a medium or large size Betta. Those with smaller sizes are harder to breed because you have to find an even smaller female Betta.

2/ During mating, if you find that the female Betta was larger and flared at the male Betta continuously, and even worse, chased the male Betta away, stop the breeding immediately. There mating and breeding will be unlikely to success.

3/ Female Bettas will drop its own eggs without mating if it's too ripe. Don't waste it.

Betta Spawn Log : BSL20180323 : HMPK Super Red (M) x HMPK Red Base (S)

While we can't get a pair of HMPK super red, the closet we can obtain is a female Betta with red base. We suspected both Bettas are siblings as we bought both at the same time from a local breeder.

Male: HMPK Super Red
Age: 3+ months
Temperaments: Aggressive.
Size: Small (3.0cm body only)
Grade: C

Nothing much we can say about this male, not the best body shape we've seen and it crooked a bit. But for the price we paid for, nothing to complain about.


Female: HMPK Red Base
Age: 3+ months
Temperaments: Aggressive.
Size: Small (2.5cm body only)
Grade: C

We've noticed the female Betta compared to other female we have, seemed a bit more aggressive than usual even though the body size was thinner but longer.


Log Notes
2018-03-14
The male and female Bettas have arrived and as usual, the unpacking, acclimating, quarantining, and conditioning the pair in the breeding tank.

2018-03-23
Mating was aggressive. Something new we observed when mating, the male Betta will bite and chase the female Betta during mating, even though it was successfully. This was repeated for several times and we concluded that both these Bettas were aggressive in their original nature (both were siblings and from the same spawn). The photo below shows that the female Betta with damaged fins due to the biting by the male Betta.


2018-03-24
The female Betta was removed and put into quarantine tank for recovering. Meanwhile, the male Betta was busying making more bubbles. We also added some water flea for the male to eat.

2018-03-25
We noticed the male was still hiding under the bubble nest but not making any new bubbles. To our surprised, there were less bubbles in the bubble nest and we suspected that the male Betta may have eaten these eggs. Or maybe the male Betta confused the water flea with the eggs? Or maybe the eggs were not fertilized properly? Perhaps feeding the male Betta during these period was not a good idea as it will ignore any foods.

2018-03-26
The male Betta was making more bubbles and we saw one or two fry swimming vertically. Maybe there was still hope that some eggs finally hatched. We'll keep our finger crossed.


2018-03-27
We found a few fry free swimming in the breeding tank but the number was quite low, roughly less than ten. Upon seeing that, Baby Brine Shrimp (BBS) was given to the fry. Let's hope that those ten will survive.

2018-04-17
We've checked the breeding tank and found no surviving fry. Several white spots were found on the Operculum area and it's best to clean up the tank and quarantine the male Betta ASAP.

Retrospection

1/ When you bought a pair of male and female Betta at a unbelievable price, most likely the pair have been used for breeding. Hence, subsequent breeding will result in lower or no fry count. Always check with the seller whether the female Betta is still a "virgin" female.

2/ Leaving father with fry method doesn't have good fry surviving rate if the male Betta and water quality of the breeding tank was sub-par.

Betta Spawn Log : BSL20180319 : Giant Blue + Red (M) x Giant Red (S)

Another breeding project involving another pair of Giant Bettas. Nothing particular interesting about this pair but body shape and colour-wise, it's better than the other pair, BSL20180315. Since we have another pair, why not just breed the sake out of it?

Male: Giant Blue
Age: 4+ months
Temperaments: Aggressive.
Size: Medium (4.0cm body only)
Grade: B+

The best looking Giant Betta we have, good colours (a bit like metallic blue but not the red wash) and body shape. Unfortunately, the photo below doesn't do the justice of the male Betta.


Female: Giant Red
Age: 3+ months
Temperaments: Fast.
Size: Medium (3.0cm body only)
Grade: B+

The only full colour Giant Betta we have and good symmetric body shape. Nothing much particular noticeable about this female Betta. Yet again, the photo doesn't do the justice to the fish.



Log Notes
2018-03-19
Mating was performed by the Giant pairs during midnight, hence we don't really saw the whole courting, tagging, biting, and mating ritual.

2018-03-20
We decided to jar the female Betta but kept it in the breeding tank. Just want to try a different approach on keeping the male and female together, although separated.

2018-03-25
The male Betta seemed a bit stressed and lingered and rested near the female Betta. Off course, there was the usual faring among the pair but nothing much. We're not sure why the male Betta picked a resting place so near to the female Betta.

2018-03-26
Added more water to the breeding tank. It was infected with Green Algae but nothing to be concerned about. However, fry count was quite low, roughly around 10-plus. Furthermore, the size of the fry was too small compare to other spawn started roughly the same time. Maybe because the female Betta was around and causing some stress to the male Betta and it started to eat its own fry. One thing we noticed, the male Betta was not an active father and mostly spent its time floating around.

2018-03-28
No fry was found. We've decided to clean up the whole breeding tank. Both the male and female was doing just fine and swimming around. Both the Bettas were placed in the same breeding tank. No plan to breed both and it's time just wait for the male to make bubbles and the female was ready.

2018-04-02
Both the male and female Bettas were sick. We removed the female Bettas into its own quarantine tank with Methylene blue. The male Betta still remains in the breeding tank with Indian Almond leaves extract. The male Betta seemed to have a swollen lip and we suspected that it may injured itself or maybe the recent water changes. We also found a snail within the breeding tank and removed it immediately.

2018-04-06
The female Betta did not survived after removing it from the breeding tank and into quarantine tank. Sad to say, this kind of affect our other breeding plan where we've acquired a Giant red male Betta. Having a pair of red Bettas should allow us to breed a bunch of red offspring.

2018-04-07
While feeding the male Betta, to our surprised, we spotted the only surviving fry within the breeding tank and we thought none have survived even after 90% full water changed. The male Betta kept chasing the little fry and to prevent it from eating it, we decided to transfer the poor little fry to different breeding tank, BSL20180310. We believe this particular breeding tank is suitable as the fry within the tank have tremendously growth compare to other breeding tank. Let's hope it will survive though this coming months. We will know after all the fry have grow up.


2018-04-17
Moved the male Betta from the breeding tank into smaller jar. Breeding tank was cleaned and stored for future breeding project.

Retrospection
1/ If the number of try was too low, maybe it's best to move the fry to other breeding tank with more fry.

2/ Having the female Betta around the breeding tank even after post-breeding may not be a wise choice. It seemed to affect the male Betta and causing unnecessary stress to the male Betta.

This Week I Learned 2018 - Week 11

Last week post or something from the past.

Another week, another compilation of vocabulary list. The list of words were a bit tricky to cohere (一致,连贯) together into a convincing paragraph. Just let your imagination go wild then!
The island have been inhabited (居住在) by the isolated indigenous (土著) peoples since long before it was discovered by foreign outsider. Strangely enough, the tribe was hospitable (好客的) and willing to embrace outsider even though there was some resistant initially. People in the island are not herbivore (草食动物) due to the climate and available food source. Within the cold climate with little greens available, tuna fish is their daily source of protein. Tuna fish, due to its distinct smelly fishy odor inhere (存在) can lead to to halitosis (口臭), which can be quite put off to outsider. The people in the island adhere (持有信仰) to a strange religious ritual where they don't inhume (埋葬) the death but instead leave it open in the wild wrapped in Tuna fish skin in a helical (螺旋) way. Everyone was inhibited (抑制) from getting near to the burial ground forever as it will bring bad luck for those who ignore the rule.

Ask HN: Were we more productive 10, 15, or 20 years ago? The question raised was related to development works itself. Were we? When comes to web development, not really, more marketing hype and too many choices available. Furthermore, too many tools, and too many abstractions. In other words, paralysis by analysis or decision fatigue, which made us ends up doing nothing.  What worse, we were bombarded by so-called news these days which read like tabloid instead. Technology made things done faster but at a price, we're more disconnected and distracted. Or maybe we (those reaching middle age) are more grumpier.

The Pilot System rule. The first system will always developed incorrectly somehow due to lacking of understanding and edge cases. Focus on the programmer productivity instead of focusing on optimizing the system itself.

Lesson learned when breeding Betta fish. We've made a few mistakes by our self and pretty much can relate to the breeder himself.

While we're talking about fish, the best video so far on using salt in your aquarium or towards your fish. We must be using salt wrongly, no salts are created equally, even chemical components are different!

Betta Spawn Log : BSL20180316 : HMPK Super Red (S) x HMPK Blue (S)

Size does matter! One of the difficulty in breeding Betta fish is the male size. If you have a small male Betta, it's very hard for the male to mate and breed with the female Betta. Generally, the female Betta will become more aggressive and attack the male Betta instead. This was the case here for this particular small male.

Male: HMPK Super Red
Age: 3+ months
Temperaments: Fast and very aggressive.
Size: Small (2.5cm body only)
Grade: B+

We were thinking maybe the small size because this male was still a juvenile. But after one month of observation and being well fed, the body size still remains the same. Hence, our conclusion this was a mature male Betta but with smaller body size.



Female: HMPK Blue
Age: 3+ months
Temperaments: Quiet and passive.
Size: Small (2.0cm body only)
Grade: C

The second smallest female Betta in our collection. Yet, we think it was a suitable choice for the small size male. While we can't see vertically stripe lines and any eggs from this female, we believe this female can mate with the male. Colour-wise, it's unimpressive with dark blue although the body shape was quite nice.



Log Notes
2018-03-14
Let the blue female Betta into the breeding tank. The male was very playful with the female but not attacking it in any possible way. We thought history going to repeat itself again where both fishes will flare each other but will not mate.We leave it as it without any interference.

2018-03-17
Since there was not eggs produced and the blue female Betta was inactive at the corner, we replaced the female with another super red female Betta. As usual, using the same water from the breeding tank, quarantined the blue Female for a few days before we relocated it back to the sorority community tank.

2018-03-18
We're surprised to find out that fry were hatching and swim vertically this morning. We thought that the original pair failed to mate. The next step was to remove the other female Betta super red from the breeding tank immediately. The poor super red female Betta was bitten quite a few times and its fins was somehow damaged due to our oversight. Note to self, check the bubble nest properly with good light source. Maybe the bubble wrap was not a good choice for a base of bubble nest, it was hard to observe any eggs.


2018-03-21
The male Betta was busy gathering and tendering the fry. We were cautious and careful about the male Betta eating up the whole spawn.


2018-04-17
Since last week, fry count was substantial low and the counting today indicate it was left with 3 to 5 fry. The surviving fry was in good shape but we wonder how many will survive in coming weeks. There was plan to move all the fry to the BSL20180310 breeding tank.

However, we've cleaned up the breeding tank and jarred the male Betta. Four fry was moved to BSL20180313 instead.

Retrospection
1/ Another failure with leaving father with fry method. There was quite a large number of fry initially but right now only four left. The plan to breed Super Red Betta did not go as plan. For the next breeding project involving this male Betta, will try with different method.

Betta Spawn Log : BSL20180315 : Giant Dark Blue (M) x Giant Galaxy (S)

After numerous attempts to mate two giant Bettas, we've finally found success with this particular pair. Compare to other types of Bettas, the giant Betta was probably the hardest to breed. First, it's hard to find good enough quality with reasonable price giant Betta (this is so true for female Betta). Second, giant Betta needs large tanks for growth compare to normal Betta, thus breeding this type of Betta without enough large tanks or plastic bottle is not recommended. Third, they have big appetite and thus additional costs in fish food. The nice thing about giant Betta is that they grow very fast and definitely a good choice for those who have big aquarium tank.

Male: Giant Dark Blue
Age: 4+ months
Temperaments: Aggressive but clumsy as well.
Size: Medium (4.5cm body only)
Grade: B

This male Betta was not our first choice but we failed to breed the female Betta below with other male Betta. And this male Betta seemed very compatible with the female Betta without trying to kill each other.


Female: Giant Galaxy
Age: 3+ months
Temperaments: Fast.
Size: Medium (3.0cm body only)
Grade: B+

Overall we love this female Betta, the body size is nice and balance. It was a lucky purchase from local breeder who were willing to let go a few female giant Bettas at an acceptable price. One unique characteristic about this Betta is this is one hell of fast swimmer. We've tried to mate her with three different male Betta and all of these males were unable to catch up with this female Betta. Only on one unlucky incident, its tail fin was bitten off by an very aggressive Giant male.


Log Notes
2018-03-15
Both male and female Bettas were overly nice with each other and we thought both going to mate soon. Little we realized that both already mated and numerous eggs have been fertilized. The spawn seemed good enough. We decided to keep the female for a while as it's still mingling with the male Betta (suspect maybe to continue mating). Even the eggs were larger that normal Betta eggs (see photo below).


2018-05-20
Decided to clean up the breeding tank. We've moved the male Betta from the tank into another smaller quarantine tank. The remaining fry were moved into another breeding tank. We've counted and found that only 9 managed to survive for this breeding project. These remaining fry have been moved to BSL20180316 breeding tank.

Introspection
1/ Moved the fry into a smaller tank for easy feeding. If the breeding was too big and the number of fry was low, it's quite difficult for the fry to find or chase the Baby Brine Shrimp (BBS).

2/ One good way to detect whether these fry was being fed accordingly was checking their growth rate or body size. If the body size was too small even after a few weeks, meaning that these fry did not have adequate food.

Betta Spawn Log : BSL20180315 : HM Red Base (M) x HMPK Blue (S)

This was a pending breeding project. We've tried to breed the male Betta with the same female for a few times but it was not working. The female Betta was full with eggs and ready to mate. But somehow it never worked out between both fishes. Then we switched to another female Betta and surprising they mated. We were waiting for vertically lines from the female Betta but none was observed.

Male: HM Red Base
Age: 4+ months
Temperaments: Aggressive and fast.
Size: Medium (3.5cm body only)
Grade: B

The male Betta was an interesting one indeed. Originally we bought it together with a few female Bettas assuming that it was a female as well. Then we just put it into the community tank thinking that it can integrate with other fishes. We didn't pay much attention until there was an Ich outbreak. We managed to quarantine it and only realized that this Betta as actually a male Betta. Furthermore, it also survived a Popeye disease. We did a full water changes together with Methylene Blue on almost daily basis.



Female: HMPK Blue

Age: 3+ months
Temperaments: Normal
Size: Medium (3.0cm body only)
Grade: B

We can't think of anything about the female Betta. Unimpressive among all the females, hence we use it to breed with this male.


Log Notes
2018-03-15
The eggs have been moved to the bubble nest. We also noticed some aggression of the male Betta towards the female Betta. Thus, we took out the female and quarantine it. The breeding tank was infected with Green Algae but we decided nothing should be done so far.


2018-03-16
The male Betta moved all the eggs to another bubble nest under the Amazon Frogbit plant. We suspected that we frightened the male when we extracted the female out from the breeding tank. We did some cleaning on the tank to remove the green algae.


2018-03-18
The male Betta moved or created another bubble nest after we cleaned up the aquarium tank due to Green Algae.



Betta Spawn Log : BSL20180313 : HM Yellow Dragon (M) x HMPK Marble (S)

One of the hardest breeding project. The poor male Betta have been rejected twice by two different female Bettas until the third female Betta. We seldom see yellow dragon, hence we bought him to our collection. Personally, I'm not a fan of HM (Half-Moon) and CT (Crown Tail), compare to PK (Plakat), those former two types are harder to keep.

Male: HM Yellow Dragon
Age: 3+ months
Temperaments: Curious and aggressive.
Size: Medium (3.5cm body only)
Grade: B

Under good lighting, any metallic Betta (called Dragon) will shine through your aquarium (the crappy and shaky photo shown below really does not justify it). We didn't realize that until we have moved the male Betta to a bigger aquarium under a good LED lighting. Expect more Dragon Betta in future, most likely a PK.



Female : HMPK Marble
Age: 3+ months
Temperaments: Active and curious.
Size: Small (2.5 cm body only)
Grade: C

Nothing particular interesting about the female Betta. We put her in as we've noticed she was physically ready to spawn as there are many eggs under the belly.


Log Notes
2018-02-16
Found this yellow dragon and decided to acquire it during our trip back to city. While I'm not much a fan of HM, but my SO seemed to like this rare yellowish HM Dragon Betta.

2018-03-09
We've decided to remove the yellow tail female PK as the poor fish have been suffered enough. The was no way that this pair will mate and we have tried for several weeks. Pity though, is hard to find the same tail colour. The male was really fond of this female and tried its best to mate with the female but things just don't work out between this pair. See the damaged to the fins. The female have been taken out and put into quarantine tank for recovering and was doing well. Reflecting back, we did not put any Indian Almond leaves extract to the breeding tank, maybe that was why the female Betta was not ready to mate.


2018-03-13
Finally the poor male Betta mated with a female, most likely during midnight till early morning. Interestingly, the male built the bubble nest next to the bubble wrap instead of underneath it. The male seemed quite happy and actively repairing the nest. We moved the female Betta from the breeding tank into a jar.


2018-03-14
The male Betta rebuilt and moved the bubble nest under the bubble wrap. Everything seemed to be in right order. We're just waiting for these eggs to hatch.


2018-03-15
Even more bubble created making the bubble nest even taller. The fry starts to swim vertically and this is quite a large spawn. We're not sure how the male Betta going to behave and we hope more fry will survive.


2018-03-20
Daily feeding of BBS to the fry. Due to our busy schedule, we can only feed the fry once per day. Typically, at minimum, the fry should be fed at least twice per day.


2018-03-25
The number of fry in the breeding tank somehow reduced a bit compare to last time but the number still quite a lot. The male Betta was idle most of the time and making some bubbles from time to time. But is too early to tell whether the male Betta will slowly eat up all the remaining fry.



2018-04-23
The yellow dragon succumbed to illness and was not able to make it. We've cleaned up the breeding tank and did a 95% water change and the fry are all doing well.


This Week I Learned 2018 - Week 10

Last week post or something from the past.

More movement this week. Daily walking steps have increased from normal average. Most likely due to some extra house cleaning here and there.


Something new this week. I've learning two words on almost daily basis for the past few months. To further reinforce my understanding, I will start writing a small paragraph using all these words. It may sounds forceful but it's quite fun as it will test your creativity and understanding. Yes, the writing and word choice can definitely be improved.
Unusually fat, tall but handsome, nobody will suspect Dr. Lee was a habitant (居住者) of a athletes' village that produces world class gymnast. As the only doctor who specialized in gynecology (妇科) and obstetrics (产科) in that area, his clinic is thriving (兴旺) with patients and business is good. While Dr. Lee still remain unmarried, he is currently cohabit (同居) with his girlfriend, May, for last five years. When they first met, Dr. Lee was muscular, charismatic, exciting, and fun at first. But things have changed all these years. He was grandiose (浮夸的), self-centered, and controlling. Little she was aware or choose to ignore that her future Mr.Right is actually a misogynist (厌恶女人的人). Worse, her future husband does not believe in monogyny (一夫一妻制) but rather polygyny (一夫多妻制). A little birdie have told May that Dr. Lee have already married and have a few kids at his hometown. Yet, she choose to ignore it and treat it as rumour due to jealously.

New T5 LED light installation leads to outbreaks of aquarium algae in a few aquarium tanks. To rectify, the usual water changes, siphon, scrubbing, and turning off the light did help a bit. Our observation and suspicion leads us to believe that it may be caused by infected aquarium plants or fishes (not enough time for quarantine) and non-stop exposure to light.

Meanwhile, I've created and started a Betta fish spawn logs page. It's pointless where your notes were scattered all over the places and it's best to just consolidate all the information into one page.

Over-justification effect. That is what happens when your hobbies or passions become your work. Nothing but discipline to proceed ahead or just to move on to something else.

Best project management practice in 2018?. The discussion on Scrum itself is honestly so true that many organizations are just practicing cargo-cult agile. Also it also depends on the type of project, there are certain systems (health, military, and etc) that cannot be developed in an Agile way. Maybe the WhatsApp approach in the right way as shared by its Engineer? Reading through the The Mythical Man-Month these days again felt like reading a satire.

Betta Spawn Log : BSL20180310 : HM Tri-band (M) x HMPK Marble (S)

The male HM Tri-band is the most expensive Betta we've purchased. Originally from Thailand, we've heard that certain purchased Betta fishes from there cannot be used for breeding. Some local breeder concluded that these fishes may have been sterilized to make them infertile before shipping to oversea customers. Or it may due to X-Ray in the airport that cause infertility. I'm not sure how true is this. Therefore, we've decided to give it a try.

Male: HM Tri-band
Age: 6+ months
Temperaments: Petite, gentle, and clumsy.
Size: Medium (3cm body only)
Grade: B

I'm personally not a fan of HM, especially small size HM. It's quite painful to watch it swims around as the long fins was holding it back and the fish was struggling. It's like walking while dragging a long wet cloth. While the colour was pretty, the fish movement was quite clumsy. Yes, also the fins rot issue (see photos below), which was partly our fault.



Female : HMPK Marble
Age: 3+ months
Temperaments: Normal.
Size: Small (2.5 cm body only)
Grade: C

Probably the ugliest female Betta in our collection. Grayish white but good body shape and fins. We must be crazy to mate a Triband with a colourless rejected female Betta. What the heck!

Another purchased which was picked by our family member. Again, I'm not a fan of HM but the Tri-band HM was quite rare to find here although the price can be better somehow. This photo below shown the usual acclimating of any new fish to the aquarium tank so the fish can adjust its body temperature to the new water environment.


2018-03-10
Mating was long and slow. It seemed both were struggling to mount with each other. This was going on for several hours and we can't seem to see any eggs. We decided to leave both fishes alone as we're not sure both will mate successfully. Few hours later, we checked again and noticed there were some eggs but the tank was infected with Green Algae and we can't see anything. One way to tell was the female Betta was hiding in the aquarium plant and sometimes the male Betta will chased it away. We quickly removed the female Betta from the breeding tank into a quarantine tank. This was one instance where the female Betta left the breeding tank without any damaged fins.

2018-03-13
The fry have hatched and we can see quite a number were swimming vertically. Not a big spawn, guestimation was around maybe 30-plus fry. Most of these fry were swimming at the four edges of the aquarium.


2018-03-25
The whole breeding tank was infected with Green Algae but the fry and the male Betta still doing well. However, we noticed the male Betta seemed breathing quite heavily but it's still moving around and kept making bubbles at its bubble nest. We decided to keep the breeding tank as it and will remove the Green Algae if needed and add more water. We're curious how the male Betta and the fry will hold up in such infected water environment.


2018-04-06
We decided to remove the male Betta into quarantine tank as we noticed he have been showing symptoms of Dropsy, swelling of belly and not active. It's condition doesn't looks good and we don't have any Indian Almond leaves with us, so we decided to use Methylene Blue and aquarium salt for now.

2018-04-09
The male Betta did not make it. However, the fry within the breeding tank were doing quite well, too well. As usual, we did a 90% water change to keep the fry healthy.

2018-05-05
Of all the spawn, this particular one have the most abnormal growing rate. If you compare the size of the young Betta, some growth way faster than others as shown in picture below. We called this one BYG (Blue Yellow Giant). The growth of BYG was noticeable since young when compare to other spawns which were started around the same time (just a few days differences). We were wondering if the growth of Green Algae was the cause but similarly, other breeding tanks also have the same amount of Green Algae and floating plants. Perhaps, it's related to particular genetic.





Betta Spawn Log : BSL20180308 : HMPK Yellow (M) x HMPK Marble (S)

The reason for this spawn was to keep the male Betta "Banana" occupied so the male Betta can have an active lifestyle while taking care of its fry. Banana have been with us for quite some time and we decided to let him starts his own family. From our experience, having the male Betta taking care of the fry made them more active and happier.

Male: HMPK Yellow
Age: 7+ months
Temperaments: Relaxed, peaceful, and quiet.
Size: Medium (3.5cm body only)
Grade: B




One of our longest living male Betta in the collection. Initially we have doubt about its gender as it seemed to mix well with different Betta either male or female (in a big aquarium tank) and does not show any aggressiveness towards other fishes in the tank.

Female : HMPK Marble
Age: 3+ months
Temperaments: Active and curious.
Size: Small (2.5 cm body only)
Grade: C


Log Notes
2018-03-07
The female was released into the breeding tank after the male failed to mate with another female giant. Initial tagging was observed and as usual, the female was hiding within the aquarium plants. We decided to keep it as it as the aquarium plants were sufficient enough as the hiding place for the female. A glass of Indian Almond leaves was used to condition the pair.

2018-03-08
Mating occurred around 9-something PM. The male having difficulty mounting the female due to lack of experiences. However, mating was successfully and a small number of eggs produced. Contrary to common male behaviour, the female was the one busy picking up the eggs into the bubble nest. The male was not taking part in collecting the eggs. Female was removed and put into another isolated tank for 7 days quarantine before we put her back to the sorority community tank.

2018-03-09
We noticed that quite a number of eggs have been missing from from the bubble nest. Suspected that the male Betta may have eaten some of these eggs (most likely infertile eggs). The male seemed like less active or enthusiast compare to other male Betta when comes to taking care of their fry.

2018-03-10
Fry started to hatch and hang tail-down. The male started to pick them up as they swam vertically for now. Compare to yesterday, the male Betta was more attentive and busied.


Betta Spawn Log : BSL20180309 : CT Red Base (M) x HMPK Marble (S)

The only Crown Tail (CT) in our collection. CT was notorious known hard to breed and keep as it's the thin fin can easily snap or keep in place. We decided to breed this to learn more about CT in general.

Male: CT Red Base
Size: Medium
Age: 6+ months
Temperaments: Cowardice but aggressive.
Size: Medium (3cm body only)
Grade: C

More cowardly compare to other Betta male. Ironically at the same time, quite aggressive when seeing other male Betta and kept flaring non-stop. Not sure if this was a common behaviour for CT as this make is the only CT we have.



Female: HMPK Koi
Age: 3+ months
Temperaments: Aggressive
Size: Small (2.5 cm body only)
Grade: C

The most colourful (when comes to bright colour) female Betta we have. Noted the damaged fins after the breeding process. Depends on the male, sometimes the mating can be quite ugly and nasty.



Log Notes
2018-03-09
Mating was a painful process for the pair. Similar to HM, the male CT have to go through numerous times of trial and error to correctly mount the female. This was complicated when the aquarium tank was infected with Brown Algae (harmless through) but aesthetically less appealing (dirty like dirt). Furthermore, there was a quite a large lump under the anus part (the organ where a fish get rid of digested food). We're not sure exact cause for the lump but suspected it may due to mating and dirty water condition.

2018-03-10
Cleaned up the aquarium and replaced 10% of the water. The lump we saw yesterday was gone and we finally saw some eggs in the bubble nest. The male Betta was swimming and eating as usual.

2018-03-13
Saw some fry free swimming around the tank. The number was small but luckily the eggs managed to hatch. SO fed a little bit of BBS and hopefully those fry will find it and eat it. Since the tank was full of Brown Algae, most likely there are some Infosuria around? But I doubt so, the survival rate of this spawn is quite low due to water quality and infected male Betta. We will wait and let nature takes its course. Screenshot below shown one of the hatched fry.


2018-03-20
We can't seemed to find any fry left in the tank and we suspected that the male Betta may have eaten all. Maybe some were hiding within the floating aquarium tank? Will keep monitoring.

2018-03-21
No fry found after searching through the floating plants. We assumed this breeding spawn failed as the fry did not manage to make it.

2018-03-24
Jarred the male and clean up the whole breeding. As usual, for treatment, added Methylene Blue with aquarium salt to its new quarantine tank.

2018-03-25
The male Betta seemed doing quite well in the quarantine tank and started to make bubbles again. This was a good sign and it's adjusting and recovering to the new environment.



Retrospection
1/ Study and aware of what kind of personality your male Betta fish. Those male Bettas which were easily scared or cowardice, the leaving father with fry method may not work that well. Once these male Bettas were spooked, they may start to eat their own fry. Maybe playing with the male Betta from time to time like poking it with a stick or your own hand could increased its confidence. Trains its aggressiveness. 

2/ Covered or shielded your breeding tank from other fishes. Add more Indian Almond leaves extract to create a dark water type of environment. This ensures the male Bettas was not disturbed and spooked.

3/ If you noticed the male Betta was sicked, in this case, the lump under its anal area, immediately removed, jarred, and quarantined the fish. Gave it immediate treatment as well.

4/ Water quality. Brown algae was not a good sign of good water quality. Perhaps next time we should immediately extract the fry to a new tank. Or perhaps, changed 50% of the water. In the past in other spawns, we've accidentally moved a few fry from one spawn to another, and the fry seemed to have survived well.

5/ Not all male Bettas are suitable for leaving father with fry breeding method. Observe and understand each fish's personality.
