Koi Betta Breeding
Koi Bettas are difficult to breed in captivity. They are mouthbrooders, meaning the female will carry the eggs in her mouth until they hatch. The fry is then released into the water, where they must fend for themselves.
It is best to keep a group to increase the chances of breeding. The ratio of males to females should be 1:2. The male will then choose a mate, and the two will spawn.
The female will lay up to 1000 eggs, which she will then pick up in her mouth. The eggs will hatch in about 24 hours, and the fry will be released into the water.
The fry is tiny and can be challenging to care for. They must be fed live food, such as baby brine shrimp or daphnia. Providing plenty of hiding places is also essential, as they are susceptible to predation.
It can be difficult to breed in captivity, but it is possible with the right conditions and care.
