should the map fish pay attention to after spawning? 1. Isolate the parent fish: After spawning, the map fish should first separate the parent fish from the eggs. The map fish does not have the habit of protecting the eggs. If the breeder does not isolate them in time, the eggs will soon be eaten by them. In isolation, it is better to separate the male fish from the female fish, so that the breeder can feed some nutritious food to the female fish separately.
2. Maintain the stability of the environment: The eggs will be hatched after fertilization. They need to be hatched in a stable environment. Therefore, the breeder needs to ensure that the water quality for hatching is clean and the water temperature is 26 ℃.
3. Identify unfertilized fish eggs: The fish eggs of map fish are larger than ordinary fish eggs. If the fertilization is successful, a small black spot will appear in the center of the fish eggs. If the fertilization is not successful, the fish eggs will be pure white. The breeder needs to fish out the unfertilized fish eggs to avoid mildew.
the map fish after spawning? After spawning, the map fish should first fish out the eggs that fail to fertilize, and then keep the water temperature at 26 ℃. Although the higher the temperature, the faster the hatching speed of the map fish eggs, the quality of the eggs hatched at high temperature will be worse. During the incubation period, do not change the water easily, because when the water quality changes dramatically, the eggs will also be affected. When the water temperature and water quality are suitable, the eggs can be hatched successfully in about 2-3 days.
