1. Quiet environment: zebrafish are easy to be frightened, especially during breeding. Therefore, in the process of breeding, breeders need to ensure that the surrounding environment is quiet and there is not too much noise.

2, environmental stability: Although zebrafish has strong adaptability and low requirements for the environment, breeders should ensure the stability of their living environment when breeding. Avoid too much temperature difference or water quality fluctuation affecting their reproduction and mating.

3. Isolate in time: Zebrafish has no habit of protecting eggs after production, and parent fish may eat their eggs as food after production. After they breed, it is best for breeders to separate their parent fish from their eggs after they give birth.

1. Parent fish: Zebrafish need to be transferred to a separate container for breeding after reproduction, because newly bred zebrafish are weak, and breeders need to feed them more high-nutrition foods, so as to speed up their recovery. It can also prevent other fish from chasing their parent fish again.

2. Fish eggs: Fish eggs produced by zebrafish can be hatched directly in the breeding tank. During hatching, the water temperature in the breeding tank should be kept between 24-26 ℃. If conditions permit, it is recommended to install a heating rod for constant temperature. The water quality should also be kept clean and fresh, and try not to change the water before the fish eggs hatch.
