Small goldfish will lay eggs when they are adults, and as long as they are mature goldfish, they will lay eggs. However, goldfish do not reproduce frequently. They usually reproduce once a year, and most of them lay eggs in spring every year. Due to the different warming time in different regions, the specific spawning time is also different.
2. How do small goldfish lay eggs1. Choose parent fish: If you want small goldfish to lay eggs, you should choose mature parent fish. The parent fish should be bright in color, complete in body shape and healthy in body. Female fish can choose 2-3 years old, and male fish can choose 1-2 years old.
2. Adjust the breeding environment: After selecting the parent fish, the breeder should arrange the breeding environment. First, prepare a separate fish tank, then put some aquatic plants, and finally install heating rods. If conditions permit, the breeding tank can be transferred to a place with sufficient light, which can increase the egg production of goldfish.
3. Pairing: Goldfish will pair themselves after estrus, and the male fish will keep chasing the female fish during pairing. Before giving birth, the male fish also uses his head or mouth to top the belly of the female fish. When goldfish breed, the female fish throws out the eggs first, and the male fish inseminate again. At this time, the eggs will become fertilized eggs.
4. Hatching: After the fish eggs become fertilized eggs, the breeder should keep the water temperature constant. Fish eggs can hatch small fish in a stable environment in about 3-5 days.
