Sunfish grow in the water temperature between 20-30 ℃. They do not require high temperature, and they can survive as long as the water temperature is between 1-38 ℃ at ordinary times. Moreover, they have strong ability to resist low temperature. As long as the water temperature is above 2 ℃, they can safely spend the winter. In other seasons, they don't require very high water temperature. As long as the water temperature is above 20 ℃, they can grow well. When breeding, it is necessary to keep the water temperature constant, try not to let the water temperature change too much, and avoid discomfort of sunfish.

Sunfish is an omnivorous fish, and there are many kinds of food that can be eaten. If it is artificially cultured sunfish, it can be fed with animal feed, plant feed and synthetic feed, which can not only ensure their adequate nutrition, but also maintain balanced nutrition. The animal feed suitable for sunfish is small fish, shrimp, mollusk, aquatic insects and so on. Plant feeds suitable for them include algae, aquatic plants, duckweed and so on. In addition, some synthetic feeds can be fed, but they need to be fed together with animal feeds.

Sunfish feed different foods at different stages. They need more nutrition in their infancy, so they need to feed more animal feed. In adulthood, the demand for nutrition will be reduced, and the animal feed fed can also be reduced.
