Mickey fish can't give birth to all the small fish in their abdomen at one time. Other fish only need to release the eggs in their bodies when they give birth, so they can give birth at one time. The Mickey fish is an ovoviviparous fish, and its reproductive process is very hard. During pregnancy, the mother provides all the nutrients the young fish need. And it gives birth to a small fry that has already formed, which is more laborious than ordinary fish. Pregnancy and childbirth both require a lot of physical energy, so they can not be completed at one time. Most Mickey fish are produced intermittently, stopping for a period of time after each production. Wait for its physical strength to recover slightly before the next birth. By observing the degree of fetal spots and bulging on its stomach, we can judge whether it has completed the birth.
Mickey fish reproduction speed is very fast, as long as the sexual maturity can be reproduced. Juveniles are usually able to reproduce when they are one month old. Mickey fish produce small fry directly, so its reproduction is less than that of ordinary fish. Mature Mickey fish can complete 3 to 4 times of production in a month. In general, mature Mickey fish can produce 30 to 40 small fry at a time, up to 50.
