. Generally, goldfish can live for 6-7 years. If the environment is good and the food is sufficient, it is possible to live for 10 years. The life span of goldfish is also closely related to the species. The life span of grass goldfish is longer than that of ordinary goldfish, because their genes are most similar to those of primitive goldfish, and their resistance is stronger than that of ordinary goldfish.
But there are also relatively short life span, such as lion head, blisters and so on, which belong to the variant goldfish, because the variant is more complex, so the life span is shorter. Ordinary goldfish begin to fade after about 7 years of breeding, and their bodies will gradually become old, so they will be abandoned by breeders after 6-7 years of breeding.
big can goldfish grow? Different species of goldfish have different sizes. For example, the size of grass goldfish is bigger than that of ordinary goldfish. It can grow up to about 40 centimeters, while ordinary goldfish can only grow up to about 30 centimeters. The size of goldfish has a lot to do with the environment in which it is raised. If it is raised in a fish tank, it can only grow to 20-30 centimeters. If it is raised in the wild or in a pond, it can grow to more than 30 centimeters. The size of the goldfish also has a lot to do with feeding. If the breeder does not give them enough food during the development of the small goldfish, the size of the goldfish will also be affected and the goldfish will not grow up normally.
