Redear sunfish

The Redear sunfish (Lepomis microlophus) is a freshwater fish known for its distinctive appearance, highlighted by its olive-green to dark green back, light yellow to orange belly, and a notable red or orange edge on its opercular flap, which gives the fish its name. Originating from the southeastern United States, this species is recognizable by its compressed, rounded body and small mouth. While it's not as famous in the aquarium hobby as some other fish, the Redear sunfish is appreciated by anglers and occasionally kept by enthusiasts who enjoy native or larger tank setups.
