Redbreast Sunfish

The Redbreast Sunfish is native to Pennsylvania's Atlantic slope watersheds and is known as Pennsylvania's 'river sunfish.'
They prefer stream and river (lotic) habitats over lakes and ponds, making them uncommon in lentic environments and absent from the Ohio River and Lake Erie drainages.
Scientific Name: Lepomis auritus
- Distinguished by their long, dark gill flap (longer than most other sunfish), blue-green to olive back with indistinct dark vertical bands, and deep orange to reddish belly that gives them their name.
- The tail is slightly forked rather than rounded like most sunfish.
- In Pennsylvania, they grow slowly, reaching about 7 inches at 4 years old and weighing 0.2 pounds, with the largest specimens exceeding 9 inches and 0.64 pounds.
