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
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.

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.

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.

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.

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

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

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.

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.
