, goldfish can give birth to small fish, but won't give birth to small fish directly, general fish is oviparous. They all lay eggs first, then fertilize them, and then the fertilized eggs hatch outside the body. Goldfish usually begin to breed in March and May. Before spawning, the belly of the female fish will appear slightly bulging, and the male fish will be more lively and active. The two fish chase each other when they are in heat. When they lay eggs, the female's body shakes constantly, and then lays many eggs. After the female lays eggs, the male discharges sperm immediately. In this way, the eggs will become fertilized eggs, which need to be hatched for 3-5 days before they become small fish. Therefore, goldfish do not directly give birth to small fish, but hatch small fish after ovulation.
the hatched goldfish? 1. Water temperature: The newly hatched goldfish have weak adaptability to the environment, so the breeder needs to give them a stable water temperature. It is better to keep the water temperature at 23 C without fluctuation.
2. Feeding: Newborn goldfish do not need to be fed. They carry enough lecithin to absorb for 3-5 days. Three or five days later, the small goldfish will swim, and the breeder can feed some cooked egg yolk. At this time, the amount of feeding does not need to be too much, and after feeding, attention should be paid to changing water, because cooked egg yolk can easily pollute the water quality, leading to bacterial growth.
