The bluehead chub has a stocky body and a very large head covered with tubercles. They have olive to brown sides often with dorsal and caudal fins orangish.
The fish pictured above is a male which can be easily identified during the breeding season because their head turns blue. The average adult size is about 5 to 6 inches long.
Bluehead chubs live in cool clear rocky streams and feed on insects and plant material. Not sure of exact range but roughly from Virginia to Louisiana in suitable habitat.
