The Dollar Sunfish is a small freshwater fish of the sunfish family. It lives in rivers, streams, and lakes in the southeastern United States and has a rounded body with a characteristic dark spot.
The dollar sunfish differs from related sunfishes in its small body size and a distinctive dark spot on the fin. It is important to nature as part of the food chain in freshwater bodies and as a consumer of small invertebrates.
Immature form that undergoes metamorphosis before adulthood.
