The mother fish will eat her own small fish. This situation is particularly evident in some fish with a large reproductive capacity. For example, guppies can produce 10-120 fish each time. It is best to isolate them in time after production. Otherwise, the mother fish will eat the small fish. Generally, black feces will be discharged after eating them.
1. Fishing out: The female fish that has just given birth to small fish needs to be fished out of the breeding tank as soon as possible. This is done as mentioned above in order to prevent the female fish from swallowing the small fish. The fish can not be immediately put back into the original tank, at this time it is still relatively weak, so it is best to rest alone for a period of time.
2. Rest: Prepare a separate fish tank. Pour the trapped old water into the tank. The water temperature must be consistent with the breeding tank. Then put the fished female fish into the tank. Let it recover its physical strength through rest. During the period, pay attention to providing sufficient bait. At the same time, change the water regularly to improve the water quality.
3. Return to the tank: After resting the female fish for a period of time, you can let it return to the original tank. In order to avoid the water temperature difference between the two tanks is too large, you can use a mild way to let the fish adapt slowly, so that there will be no problem to return to the original tank.
