Redbreast Sunfish (Lepomis auritus) lives in freshwater lakes across Eastern North America. It feeds on insects and crustaceans. Its conservation status is Least Concern.
Fascinating facts about the Redbreast Sunfish
- A 12-inch redbreast sunfish pushes the limits of panfish size, matching the record 30.5 cm (12.0 in) length and 0.79 kg (1.7 lb) weight caught in Florida's Suwannee River in 1984. That trophy, listed as the IGFA all-tackle world record, shows the species can grow far beyond the typical 11 cm (4 in) adult.
- Redbreast sunfish lay about 1 000 eggs in a shallow sand-gravel nest the male builds, but females can produce 3000 eggs, each 2.1 mm in diameter. After fertilization the male guards the nest until the fry hatch. They reach reproductive maturity in their second year and can live up to eight years.
- In the wild these fish devour mainly immature aquatic insects, with mayflies, small fish and dragonfly larvae forming the bulk of stomach contents, and they will also snap up tiny crayfish. Their opportunistic feeding puts them in direct competition with other sunfish and larger predatory fish that hunt the same prey, while big bass-type Micropterus species prey on juvenile redbreasts, shaping their survival chances in shared waters.
- The species favors vegetated, rocky pools and lake margins where overhanging branches create shade and shelter, thriving best in water with a steady current and a pH between 7.0 and 7.5. When currents drop or water becomes too acidic or alkaline, survival rates plunge, showing how tightly redbreasts are linked to water chemistry and flow.
- Beyond its native eastern U.S. and Canada, redbreast sunfish have been introduced to Germany, Italy, Mexico and Puerto Rico, where they have established breeding populations. In these new waters they often hybridize with native sunfish species, a common but poorly studied phenomenon.

About the Redbreast Sunfish
In the warm, languid waters of North America, the Redbreast Sunfish glides with effortless elegance, its reddish-orange breast patch glowing like a ember as it navigates the sun-dappled shallows. With a gentle flick of its tail, it darts between the aquatic vegetation, its bronze-hued scales catching the light and sending shimmering waves of color through the water. As it forages for insects and crustaceans, its very presence seems to embody the serene and unhurried pace of life in the freshwater realm.
