Habitat
The Tennessee dace inhabits spring-fed, first order streams that are usually less than two meters in length and shaded by woody vegetation. Woody vegetation often includes hemlock and rhododendron species. They prefer the ridge and valley limestone region. In stream habitat includes silt and fine gravel pools and undercut banks with woody debris and other material to serve as cover. Studies conducted found that root masses and other woody vegetation is critical for the survival of the Tennessee dace. Adults use root masses as cover, and young-of-the-year are often found inside of root masses. Debris that falls into streams provides additional cover.
