Warmouth Sunfish

The Warmouth Sunfish has a large mouth and red eyes.

Three or four dark stripes (like war paint) radiate back from the eye across the cheek and gill cover.

They have large dark blotches on their sides and back which do not normally form an organized pattern.

Warmouth Sunfish lack the lateral stripes of black spots seen on the rock bass.
