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!

Log Notes
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.

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.

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.

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.

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.

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.

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.

We observed that Bettas have torned fins. Mostly likely this was due to fights among the Bettas. Therefore, we decided to jar all the Betta fishes.

The jarred Bettas were growing at a good rate and we can observe significant growth rate. While there were a few which, sadly, deformed or having pop eye, most still growing at a good rate. Colour-wise, we can see triple colours at the tail but colour-wise, it's quite boring.

1/ Initially we don't want use this male Betta for breeding as we worried that HM (Half-Moon) is always quite fragile and sensitive, thus hard to keep it alive (based on our past experience). However, we decided to go ahead. However, we picked the worst possible female Betta to pair up with this male Betta and and the end result, the quality of most of these offspring were quite disappointing.

2/ Daily water changes. Again, daily water changes.
