? Goldfish reproduce by laying eggs and fertilizing. When goldfish breed, they need the right water temperature, generally 18-25 degrees Celsius is more appropriate, so goldfish usually breed in warm spring. When goldfish breed, they should not only have suitable water temperature, but also have both male and female fish reach the age suitable for breeding. Generally, male fish of 1-2 years old are suitable for reproduction, and female fish of 2-4 years old are more suitable for reproduction. If the goldfish is artificially helped to reproduce, high-protein bait should be added to the goldfish of the right age in advance to supplement nutrition for the goldfish and prevent the goldfish from getting sick. When
breeding, the male fish should be a little more, the ratio of male fish to female fish is about 3:1, so as to better fertilize the eggs. During the breeding season, the male fish will chase the female fish and touch the abdomen of the female fish. When the female fish ovulates, the male fish will be fertilized immediately. After that, the parent fish should be fished out and raised to avoid the parent fish eating the small fry. After a week, the fish will be hatched.
theory, when goldfish grow to one week old, they begin to have the ability to reproduce, and then the reproductive system of goldfish will gradually mature. The breeding interval of goldfish is relatively short, and it can breed almost once a year.
