They occur most often near woody debris, vegetation such as water willow, or large boulders (Ref. 75766). Spawning takes place in gravel shoals in later winter (Ref. 75766). Migratory behaviour is undetermined (Ref. 126106). Page, L.M. and T.J. Near 2007 A New darter from the upper Tennessee River drainage related to Percina macrocephala (Percidae: Etheostomatinae).

Differs from Percina macrocephala by having larger scales (usually 24-26 scales around the caudal peduncle vs. 27-31), 21-23 transverse scales (vs. 23-26), and 70-77 lateral scales (vs. 76-86). Has values for the combination of caudal peduncle, transverse and lateral scales and lateral scales usually 120-129 (vs. 128-141); has shorter snout on average; snout ranges from 20-28% of HL compared to 24-31 in Percina macrocephala (Ref. 75766).
