Panda rat fish is a small variety of rat fish, and its adult time is relatively early compared with other rat fish, and it usually matures within 8-12 months. When panda rat fish begins to breed, the belly of female fish will become larger than usual, and the activity will be relatively reduced, but it will not be particularly obvious. Male fish will swim back and forth in the fish tank after estrus, and the amount of activity will be more than usual, and they will look very excited. Before the female fish spawns, the male fish will keep chasing the female fish. If the female fish accepts the male fish, it will chase and play with the male fish. When breeders find them chasing each other, it is best to transfer them to the breeding tank as soon as possible.

Panda rat fish is oviparous, but their process is quite special. When the panda rat fish is mature, the male fish will keep chasing the female fish. If the female fish accepts their pursuit, the male fish will stick out his genitals and then discharge semen. Female fish will catch the semen discharged by male fish with their mouths, and then find a quiet corner to lay eggs on their own. After laying eggs, the female fish will splash semen from her mouth on the eggs, and then the eggs will be fertilized and become fertilized eggs. After a few days of hatching, the eggs will become small fish, and the small fish need to be born 2-3 days before they can swim on their own.
