without isolation? Zebrafish cannot reproduce without isolation, because they are ovoviviparous fish. If the big fish is not isolated during reproduction, it is easy for the eggs to be eaten by the big fish, which will greatly reduce the chance of successful hatching of small fish. In addition, the breeder should also pay attention to the isolation of the parent fish at the first time after the production, because at this time the parent fish has just finished production, their body is very weak, and it is very easy to eat the eggs as food to restore physical strength, so the breeder should pay special attention.
should be paid attention to when breeding zebrafish? The following problems should be paid attention to when breeding zebrafish:
1. Raise the water temperature: breeders should pay attention to raising the water temperature to about 26 degrees, which can effectively stimulate them to produce better.
2. Maintain the water quality: Although the zebrafish is not strict with the water quality at ordinary times, the water quality must be kept clean when breeding. It is better to change the water frequently, and the temperature difference should not be too large when changing the water, so as to avoid problems.
3. Isolated breeding: Zebrafish are easy to eat their own eggs after breeding, so it is better to lay aquatic plants or small stones at the bottom of the fish tank to facilitate the attachment of fish eggs. If conditions permit, a layer of protective net can also be placed in the middle and lower part of the fish tank, which can not only allow fish eggs to fall, but also prevent female fish from eating eggs.
