usually begin to spawn in spring or autumn. When spawning, the mother's abdomen will become larger, her appetite will decrease, and she will not like to move. Sometimes she hides alone at the bottom of the tank, and if other fish approach, the mother fish will expel them. The performance of the male fish is more excited, after the heat will keep chasing the female fish, and sometimes bite the female fish's buttocks. If the mother fish accepts their pursuit, she will interact with them. Moreover, during the breeding season of male fish, there are several small white spots on the bones of the front fins on both sides, which is "chasing stars". Star-chasing only occurs during the breeding season of male fish, after which they disappear on their own.
for goldfish breeding 1. Disinfection: a separate fish tank needs to be prepared for goldfish breeding. Before breeding, the breeder needs to use potassium permanganate solution to disinfect the fish tank, which can improve the hatching rate of fish eggs.
2. Aquatic plants or fish nests: Before goldfish breeding, breeders need to put aquatic plants or fish nests in the fish tank, so that the eggs produced by goldfish can be well attached to them. Moreover, after putting aquatic plants or fish nests, it can effectively prevent goldfish from eating fish eggs.
3. Reproductive ratio: The best reproductive ratio of male and female goldfish is 2:3 or 2:4, which can avoid the lack of male and semen, and also improve the fertilization rate of fish eggs.
