after spawning? The eggs of the map fish can be fished out after spawning, but the amount of reproduction of the map fish is relatively large, and the size of the eggs is relatively small, so it is difficult for the breeder to fish out all the eggs at one time. If you do not pay attention when fishing, it will also hurt the eggs, so the breeder should try not to fish out the newborn eggs. If you are afraid that the parent fish will eat the eggs, you can fish out the parent fish and isolate it. If the fish eggs must be fished out, the fish nest can be put into the breeding tank before they give birth, so that most of the fish eggs they produce will fall into the fish nest, and then the breeder will fish out the fish nest, which can reduce the damage to the fish eggs.
map fish eggs hatching is relatively simple, as long as the water quality is clean and refreshing, the water temperature is 26 C, after 2-3 days of incubation, fish eggs can hatch small fish. In the process of hatching, the breeder should fish out the unfertilized or dead eggs. Generally speaking, the unfertilized eggs are white, while the fertilized eggs have a small black spot. The breeder can judge whether the eggs are fertilized by observation. For the first three days after the hatching of the fertilized eggs, the breeder should try not to change the water, and after three days, the water can be changed once after feeding.
