Mickey fish will eat its own small fish, which mostly occurs just after Mickey fish is produced. Female fish consume a lot of energy when they produce. Therefore, after they are produced, they will be very hungry. At this time, when they see smaller fish, they will eat them as food. Even the small fish they produce are no exception. Moreover, the newborn fish are fragile, unable to escape quickly, and are easily eaten. After the female fish are produced, it is necessary to fish out the small fish in time to avoid them being eaten. Wait until the small fish have the ability to protect themselves, and then put them back to the parent fish.
