Sunfish are neither tropical nor cold water fish, they are warm water fish. Sunfish can survive in water temperatures between 1-38 ℃. Under normal circumstances, as long as the water temperature is above 2 ℃, they can spend the winter safely. So sunfish is neither tropical fish nor cold water fish. The most suitable temperature for sunfish to grow is about 20 ℃. If it is artificially cultured sunfish, the water temperature can be kept between 20-25 ℃.

1. Water temperature: Sunfish does not require high water temperature, so long as the water temperature is kept between 20-25 ℃ when artificially raised.

2. Illumination: Sunfish like illumination. When cultured artificially, it is best to put them in a place with sufficient light, so that they can receive more sunlight.

3. Feeding: Young sunfish can feed some aquatic insects, algae and backwater. When they reach adulthood, they can feed some small fish, shrimp, synthetic feed and so on. If it is family farming, you can also feed some steamed bread and rice.

4. Regular sterilization: Sunfish are prone to white spot disease, so they need to be sterilized regularly during breeding to avoid the risk of disease. It is also necessary to observe carefully and treat them in time after they are found to be sick, so as to avoid affecting the body of sunfish.
