How has the goldfish raised for three years not reproduced, how can it reproduce

No heterosexual fish: Goldfish never reproduce after maturity. It may be that there is no heterosexual fish in the fish tank. If there are only male or female fish in the fish tank, they will not reproduce by themselves. Breeders should add heterosexual fish to fish tanks and adjust their living environment. Not in breeding season: It is also possible that it is not in breeding season, and breeders can wait until spring to let them breed. Unstable environment: Although goldfish have low requirements for breeding environment, they will not reproduce if the environment is poor.

1. No heterosexual fish

1. Reason: Goldfish that have been raised for three years have not reproduced because there are no heterosexual fish in the fish tank, because goldfish need male fish to pair before they can reproduce. If there is no male or female fish in the fish tank, they will not reproduce.

2. Solution: Breeders need to observe the sex of goldfish and add heterosexual fish. It is also necessary to adjust the breeding environment to a suitable breeding range, so that goldfish can breed.

2. It is not in the breeding season

1. Reason: The goldfish raised by the breeder for 3 years may not be in the breeding season, and some goldfish mature late, which takes 1-2 years. Therefore, they have not reproduced after maturity, which may not be in the right season.

2. Solution: Goldfish breed every spring. Breeders can put them together with heterosexual fish after entering spring, which can increase their breeding probability and speed.

3. The environment is unstable

1. Reason: Goldfish never breed. It may also be because the living environment is poor or unstable. Even in the breeding season, the water temperature and water quality are always unstable, and they will not breed.

2. Solution: Breeders need to ensure that their living environment is stable, the water temperature should be kept above 22 ℃, and the water quality should be kept clean and fresh. If conditions permit, it is recommended to take oxygen for several hours every day.
