1. Water temperature: Zebrafish has strong adaptability and can grow in water temperature between 11-32 ℃. But the best temperature for them to grow is 24-26 ℃, and the breeder can install a heating rod to keep the water temperature constant.

2. Water quality: Zebrafish can adapt to a wide range of water quality, and they can grow in weak acid, weak base and neutral water. Breeders can keep the PH value between 6.5 and 7.5, and usually need to change water once every 3-5 days. It is best to control the amount of water changed every time at one third of the total water quantity. If conditions permit, a circulating filtration system can be installed to keep the water quality clean.

3. Feeding: Zebrafish has miscellaneous feeding habits, so breeders can choose to feed with animal feed and synthetic feed. This can ensure their adequate and balanced nutrition.

4. Oxygen: Zebrafish have a high demand for oxygen, so breeders need to install an oxygen pump to ensure that they have enough oxygen.

1. Environmental stability: Zebrafish are sensitive to environmental fluctuations, and breeders need to ensure that the water temperature and water quality in which they live are stable, so as to avoid discomfort or death.

2. Regular disinfection: Zebrafish have the ability to resist diseases, but breeders should also check them regularly so as to treat them in time. Disinfect regularly to avoid bacterial infection or illness.
