When Thai betta fish reproduce, it can wait for the small fish to hatch successfully before fishing out the male fish. Because they have the habit of protecting their eggs, they will always take care of their eggs before they hatch.

Male fish will discharge sperm immediately after the female fish lays eggs, and then put the fertilized eggs into the built fish nest. Until the small fish hatch successfully, they will always guard by. If fish eggs are found to fall or fish nests are broken, they will repair them. But also put the fallen fish eggs back. At ordinary times, they also fan the water with their double fins to fill the fish nest with oxygen. Thai betta males play a great role in hatching small fish, so it is best for breeders to wait for the small fish to hatch successfully before fishing them out.

When the female fish breeds, the female fish can be fished out immediately as long as the female fish lays eggs. Because female fish have no habit of protecting their eggs, and they will eat their eggs when they are hungry, and may destroy the nest built by male fish during swimming, the breeder can fish them out immediately after laying eggs. This will not only speed up their recovery, but also prevent them from affecting the hatching of small fish.
