The reproduction method of red zebrafish is oviparous. During the breeding period, put male and female fish over 5 months old into the breeding tank and maintain the water temperature at about 25°C, and they can reproduce naturally. During breeding, the female fish will release the eggs into the water, and the male fish will go to fertilize the eggs. The fertilized eggs formed are placed in water at 24°C, and small fish can hatch in 2-3 days. Red zebrafish have a very strong reproductive capacity and can reproduce approximately every 7 days. 1. How red zebrafish reproduces small fish

The reproduction method of red zebrafish is oviparous. During the breeding period, put male and female fish over 5 months old into the breeding tank, keep the water temperature around 25°C, and do not disturb them, so that they can reproduce naturally. During breeding, the female fish will release the eggs into the water, and the male fish will go to fertilize the eggs. After receiving fertilized fish eggs, small fish can hatch. 2. How to hatch fertilized eggs of red zebrafish

Put the fertilized eggs laid by red zebrafish into water at about 24℃, and they will naturally hatch into small fish in 2-3 days. If the water temperature can be raised to 28°C, it will only take about 36 hours for them to hatch. Newly hatched fish do not need feeding. After about a week, just feed them with egg yolk water. 3. How often does red zebrafish reproduce?

Red zebrafish has a very strong reproductive capacity. After their sexual functions are fully mature, they can reproduce approximately every 7 days. Generally, they can reproduce 6-7 times a year. However, in actual breeding, it is not recommended to breed them frequently, because this will lead to genetic deterioration of the offspring. Generally, breeding 1-2 times a month is enough. In addition, during the breeding period, attention should be paid to increasing nutrition for the broodstock.
