1. Why don't goldfish lay eggs

1. Immature: It is possible that goldfish don't lay eggs because they haven't reached the age of reproduction. Generally speaking, goldfish need about one year to develop and mature. Adult goldfish will lay eggs, and if they are underage goldfish, they will not lay eggs.

2. Environmental discomfort: Goldfish may not lay eggs because of uncomfortable living environment, and goldfish breed in specific seasons. Generally, goldfish start laying eggs every spring. Because the temperature warms up in spring and the temperature is relatively stable, it is more suitable for spawning. But if their living environment is still unstable in spring, they will not lay eggs.

3, No opposite sex: Although female goldfish can lay eggs on their own, if there are no opposite sex fish, they may not lay eggs. If breeders want them to breed, they'd better add heterosexual fish to the fish tank.

2. How can goldfish lay eggs

1. Choose parent fish: If you want goldfish to lay eggs, you should first choose mature male fish and female fish and raise them together.

2. Prepare breeding environment: Breeders also need to prepare a separate breeding tank and a comfortable breeding environment for them. Aquatic plants need to be added into the breeding tank, and the temperature should be kept at about 26 ℃.

3. Reproduction: After the female fish and male fish are successfully paired, the female fish will discharge eggs first, and the male fish will immediately discharge sperm. At this time, fish eggs will become fertilized eggs.

4. Hatching: After the fish eggs become fertilized eggs, the breeder can keep the water temperature constant. After waiting for about 3-5 days, the eggs will hatch small fish.
