Whether map fish can survive in spawning depends on whether the eggs are fertilized. If the eggs have been fertilized successfully, the breeder only needs to keep the water temperature constant and the water quality stable, and the eggs can hatch small fish in a few days. If the fish eggs are not fertilized, they will not survive, and the breeder needs to fish them out immediately to prevent them from molding and polluting the water quality. If you want to tell whether fish eggs are fertilized or not, you can judge by the color of fish eggs. Successful fertilized fish eggs are translucent, and there is a small black dot in the middle. If they are unfertilized fish eggs, their color is white and there are no small black spots in the middle.

1. Fish eggs: After spawning, the breeder can separate the unfertilized fish eggs first to avoid their mildew affecting water quality and other fish eggs. Then put the fertilized fish eggs in a separate container, keep the water temperature at 26 ℃, keep the water quality stable, wait for 2-3 days, and the small fish can hatch.

2, parent fish: The breeder needs to separate the parent fish from the fish eggs. Because map fish have no habit of protecting eggs and eat their eggs when they are hungry, breeders need to separate them as soon as they lay eggs. If the number of map fish raised is large, the breeder had better put the map fish in a separate container for a period of time and then put it back into the original tank. If the number of map fish raised is small, he can choose to put it back into the original tank directly.
