Zebrafish don't need to turn on the lights all the time, they don't have high requirements for lights, and too strong light may cause them more discomfort. It is best for breeders to decide when to turn on the lights according to their growing environment. If zebrafish can receive more natural light, the breeder only needs to turn on the lights for 2-4 hours every day. Breeders may not turn on the lights if they don't have enough time. If zebrafish receive little or no natural light, the breeder should keep the light on for about 10 hours.

1. Water temperature: Zebrafish does not require high water temperature. They can grow in high temperature environment and survive in low temperature environment. The breeder can keep the water temperature between 24-26 ℃ and use a heating rod to keep the water temperature constant.

2. Water quality: Zebrafish have strong adaptability to water quality, and they can grow in weak acid, weak base and neutral water. When rearing artificially, they can grow normally as long as the PH value is kept between 6.5 and 7.5.

3. Feeding: Zebrafish like animal feed. Breeders can usually feed them some good-year shrimp, red worms, paramecium, water fleas, water earthworms and other foods, and can also feed them some pellet feed or powder feed. They don't eat much, so breeders need to feed them once a day, and each time they are fed to 70% full.
