1. Environmental discomfort 1. Reason: Zebrafish may not reproduce in an unsuitable breeding environment. Although they have strong adaptability, they still have high requirements for breeding environment. If breeders do not prepare a suitable breeding environment for them, they may not reproduce all the time.
2. Solution: Breeders need to keep the water temperature between 25-26 ℃, keep the PH value between 6.5-7.5, and control the hardness of water between 6-8. Zebrafish have the habit of eating eggs, so breeders need to prepare an isolated net in advance.
2. Not old enough to reproduce1. Reason: Zebrafish never reproduce may not be mature yet, and their development has a great relationship with the environment. If the environment is suitable, their development speed will be faster.
2. Solution: Zebrafish takes 3-4 months from birth to maturity. Breeders should keep the environment stable during their development, so that they can develop better.
3. No heterosexual fish1. Reason: Zebrafish never breed. It may be that there are no heterosexual fish in the fish tank, for example, there are only male fish without female fish in the fish tank, or only female fish without male fish. This kind of situation will not reproduce.
2. Solution: The breeder needs to observe the sex of zebrafish in the fish tank, and then add zebrafish of different sexes. After they are in estrus, they can be fished out and bred separately.
