Mini parrot fish need to be isolated and cultivated together with the female fish, because after the small fish are born, they are likely to be eaten by other large fish. You can also choose to use a special breeding box, so that other fish do not need to be fished frequently. Come out and avoid unnecessary deaths. About a week after the mini parrot fish lays eggs, the small fish will hatch, but during this period, the water temperature must be maintained at 20-26 degrees. During the period when the female fish is laying eggs and the young fish are hatching, it is best not to change the water a lot and frequently. You can use siphoning to absorb fish feces and other impurities, and replace a small amount of clean water.
