Life history and habitat requirements: The green sunfish (5.9-12.2 inches) is an introduced species that prefers streams. It can tolerate greater turbidity than many other sunfishes. They feed primarily on insects but they will also eat crustaceans, fish eggs, very small fish and algae. Green sunfish spawn in the spring and summer. The green sunfish construct nests like the other sunfishes (i.e. the pumpkinseed, redbreast sunfish and bluegill), but the nests are isolated or occur in smaller groups, and are usually located in pools or along stream banks.
