? After pregnancy, the personality of a zebrafish will change. It usually shows irritability and abnormal activities. It often swims around the fish tank and sometimes chases the male fish. But some will become unusually quiet, always motionless at the bottom of the tank, and if other fish approach, they will be driven away. When a zebrafish is pregnant, its belly gets bigger and the lower part of its belly turns pink. After pregnancy, the abdomen of zebrafish is not obvious in the early stage, it looks like eating too much, and in the later stage, the abdomen will be more obvious. And the genitals will also change, as the time of pregnancy increases, their genitals will become more and more obvious.
zebrafish after pregnancy? After pregnancy, zebrafish should be kept in isolation first, and it is better to prepare a separate breeding tank for them. Prevent other fish from chasing or attacking them and scaring them. After pregnancy, zebrafish need to be properly supplemented with nutrients, preferably a small number of times, so that they can better absorb nutrients. The water temperature should be kept constant to avoid the temperature difference stimulating the zebrafish, leading to premature delivery or other dangerous situations. Usually, the amount of water change needs to be reduced, and the frequency of water change should also be reduced to avoid environmental changes stimulating them. When it is time to give birth, the breeder needs to put aquatic plants in the breeding tank so that the eggs they lay can be attached to them.
