1. Is zebrafish good at reproduction Zebrafish is relatively good at reproduction. They are oviparous fish, and they are fertilized in vitro when reproducing. When they mature, they will reproduce as long as the environment is comfortable. Under normal circumstances, zebrafish born 3-5 months can mature. Moreover, the frequency of their reproduction is relatively high. As long as the environment is suitable and the food is sufficient, they can reproduce once every 7 days and 6-7 times a year.
If the cultured zebrafish is mature but does not reproduce, it may be because there are too few heterosexual fish in the fish tank, so the breeder can focus on adding some heterosexual fish, which can make them reproduce better.
2. How do zebrafish reproduce1. Prepare a breeding tank: When zebrafish reproduce, it is best to prepare a separate breeding tank for them. If conditions permit, an isolation net can be put in the breeding tank to prevent zebrafish from eating their eggs. The temperature in the breeding tank should be kept at 24-26 ℃, and the water quality should be clean and refreshing.
2. Breeding: After the zebrafish enters the breeding season, the male fish will constantly chase the female fish, and in the process of chasing, the female fish will lay eggs. After the female fish lays eggs, the male fish will discharge sperm forward, and at this time the eggs will become fertilized eggs.
3. Hatching: After the fish eggs become fertilized eggs, the breeder can start hatching. When hatching, it is necessary to keep the water temperature at 26 ℃ and wait for 2-3 days, and the fertilized eggs can hatch small fish.
