Mickey fish can't give birth to small fish at one time, because they are oviparous fish, and their reproduction methods are special, all of which are fertilized and developed in vivo. Mickey fish is not giving birth to fish eggs, but small fish larvae. Therefore, when they are produced, they are all part of them, and then they stop for a period of time, and then they are produced again after their physical strength is restored. Under normal circumstances, Mickey fish needs 3-4 times to be completely produced. Breeders can judge whether they have finished production by the size of their bellies. If their bellies become flat, it means that they have finished production. Breeders need to fish them out as soon as possible to prevent them from hurting small fish.

Mickey fish can produce 30-40 small fish at a time, and some larger ones can produce 50 small fish at a time. Because they are oviparous, small fish will mature in the mother before being born. It takes about one month for Mickey fish to mate and reproduce. And they produce for a long time, so they breed less than other fish. Although they reproduce in small numbers, their survival rate is relatively high. When breeding Mickey fish artificially, as long as the living environment of small fish can be guaranteed to be comfortable, they generally will not die.
