Goldfish will give birth to small fish, but only after a year of growth, goldfish will mature and begin to have the ability to reproduce. Unlike mammals, goldfish are not viviparous, but oviparous, so they can not directly produce small fish. Specifically, during reproduction, the female will ovulate first, and then the male will ejaculate and fertilize the eggs, making them fertilized eggs. Under the condition of suitable water temperature, after 3-7 days, the fertilized eggs will hatch into small goldfish.
One, can goldfish give birth to small fish
? Goldfish can give birth to small goldfish, but goldfish only grows to 1 week old later, just can develop maturity, just have the ability of breed. Unlike mammals, which are viviparous, goldfish breed small goldfish directly from the female. The reproductive mode of goldfish is oviparous, in which the female lays eggs first, then the male discharges sperm to fertilize the eggs, and then the eggs hatch in a suitable environment for 3-7 days, and then grow into small fish. First of all, the reproduction
of goldfish should ensure that there are both female fish of the right age and male fish of the right age, and the number of male fish is more than that of female fish, the best ratio is 2:1 or 3:1. Usually, the most suitable female for breeding is about 2-4 weeks old, and the male can choose 1-2 weeks old. Then we need a suitable water temperature. The water temperature of 18-25 C is more suitable for the breeding of goldfish. In this water temperature range, the eggs are easy to hatch and not easy to appear deformed. This is also the reason why goldfish mostly breed in warm April-June.
When the goldfish enters the breeding season, the belly of the female fish will begin to become round, and the male fish will constantly chase the female fish and touch the female fish with his head. At this stage, we should increase the nutrition of goldfish, especially feeding high-protein feed, which can make goldfish stronger and conducive to the reproduction of goldfish.
