After laying eggs, map fish first need to identify whether they have successfully inseminated. It can be judged by the color change of fish eggs. If there are black spots in the middle of fish eggs, it means success. After successful spawning, it is necessary to maintain a suitable water temperature of about 26 ℃ to hatch fish eggs. Do not change the water in the fish tank easily. The parent fish in the water can be transferred. About 2-3 days after laying eggs, the eggs can hatch small fish. 1、 Can map fish lay eggs and live? Map fish can reproduce after reaching the age of sexual maturity. Their eggs can live in principle, but care should be taken to keep the surrounding water temperature appropriate. Fish eggs may not survive under inappropriate water temperature and other conditions. 2、 Map what fish do after spawning. In the process of reproduction, hatching after spawning is an important process. After the map fish lay eggs, we first need to identify whether these eggs have been successfully inseminated, and jump out the eggs that have not been inseminated. It can be determined by the color change of fish eggs. If there are black spots in the middle of fish eggs, it means that insemination is successful; If the egg turns white, it means failure.
After spawning, the eggs of these failed insemination fish can be separated. For successful insemination eggs, it is a very important task to maintain the appropriate water temperature around them. The higher the water temperature, the better. Specifically, it is more appropriate to be around 26 degrees. If it is above 28 degrees, although the incubation time of fish eggs will be appropriately shortened, the quality of hatched fry is very poor. The original water in the fish tank should not be replaced easily. If the water quality changes dramatically, the hatching of fry will be affected. For the original parent fish in the fish tank, they can also be taken away to avoid inadvertently eating fish eggs or small fish. When the surrounding environment is suitable, you can see the successful hatching of fish eggs in two or three days. （DeTuYuChanLuanNengHuoMa，ChanLuanHouZenMeBan）
