, goldfish can reproduce. After sexual maturity, goldfish begin to have the ability to reproduce. This time is usually after one week of age. In order for goldfish to breed by themselves, it is necessary to ensure that the water temperature in the fish tank is kept within the range of 18-22 degrees Celsius, which is suitable for goldfish breeding. At the same time, it is necessary to ensure that there are both female and male fish in the tank, otherwise there is no way to reproduce.
Generally speaking, the male fish has a slender body, a stronger tail fin, a more colorful body and a narrower excretion hole. When swimming, the female fish is usually in the front, and the male fish is usually chasing behind. When the water temperature in the fish tank is suitable and there are sexually mature female and male fish, we should pay attention to adding nutrition to the goldfish properly, which can better promote the reproduction of goldfish.
When the fry is born, it is necessary to fish out the parent fish first, otherwise it is easy to swallow the fish. At this time, we must ensure the stability of the water temperature, and the resistance of the fry at this time is still relatively weak. Generally, in the first three days or so, the fry can rely on the nutrition in the egg yolk to survive. After that, the fry slowly begins to have the ability to swim. At this time, the cooked egg yolk can be used to make a solution to feed the small goldfish. In a few days, you can gradually feed small fish and insects, and start to feed them normally.
