? Goldfish can reproduce about once a year, but this requires goldfish to grow to one week old and mature reproductive system. Goldfish's favorite breeding water temperature is 18-25 C. Goldfish breed faster and more smoothly at this temperature, so goldfish usually spawn between April and June. For artificial breeding, males should choose healthy goldfish of 1-2 weeks of age, while females should choose goldfish of 2-4 weeks of age, which has the strongest reproductive capacity. When the goldfish enters the breeding season, the male fish will constantly chase the female fish and touch the abdomen of the female fish with his own body. When the female fish ovulates, the male fish will follow behind to discharge semen and fertilize the eggs. After about a week, the fertilized eggs can become small fry.
can goldfish lay at a time? The number of eggs laid by goldfish of different ages and individuals is different. The average healthy and strong goldfish can lay thousands of eggs at a time. In the same spawning season, goldfish can spawn about 3-4 times, each time the number is not the same. Usually, the number of eggs laid in the second time is the largest, while the number of eggs laid in the first and second times is less. Younger or older goldfish lay fewer eggs at a time, and smaller, undernourished goldfish lay fewer eggs.
