? Domestic goldfish may not breed because goldfish are not old enough to breed. They are usually born for about one year before they can breed. It is also possible that there are no goldfish of the opposite sex in the fish tank, so they can not mate, so they will not reproduce. It is also possible that the environment for reproduction has not been reached. Although goldfish have strong adaptability, they need a comfortable environment for reproduction so that they can reproduce normally.
1. Suitable environment: In order to breed goldfish, it is necessary to provide them with a comfortable environment. When goldfish breed, the water temperature can be controlled at about 20 degrees Celsius. They like weak alkaline water, and the PH value is best between 7.5 and 8.0. During the breeding period of goldfish, the breeder should try to reduce the frequency of changing water and avoid the temperature difference not exceeding 1 C.
2. Male and female ratio: In order for goldfish to reproduce, it is necessary to adjust the male and female ratio so that they can mate normally. Before breeding, they can be put in according to the ratio of 2:3 between male and female, so that they can pair up by themselves.
3. Prepare the breeding tank: After they are in heat, the breeder needs to put them into the prepared breeding tank and add the fish nest in the tank. After breeding, fish out the parent fish as soon as possible and wait for the eggs to hatch by themselves.
