Today I woke to find my F1 pair of Betta sp. api api spawning. There's a very small number of eggs in the nest, but considering both male and female are only about an inch total length, I am surprised that they were able to spawn at all
Only time will tell how well the male handles the challenges of fatherhood. Hopefully the fact that he has been actively protecting his nest from the pair of Betta coccina in the tank over, bodes well for both present and future success.
Hailing from Melbourne, Australia, I currently keep and breed a number of species from the coccina complex.
