Redfin Shiner lives in low gradient streams with clean gravel and some submerged aquatic vegetation. It is native to four of 18 watersheds in western and central New York. It has declined to levels below detection in the Oswego watershed and there are also major declines in tributaries in the Ontario watershed. Its distribution mimics that of Northern Sunfish because both species use the same nesting sites. Despite declines it retains a limited distribution in the Ontario, Erie and Allegheny watersheds and it is classified as Special Concern.
