Breeding males collected in April at the type locality were most abundant in gravelly runs, while breeding females were more common in slower water over sandier substrates adjacent to runs. It is reported to be spawning in May and June in gravelly runs, burying their eggs in small sand patches among the gravel, a similar behavior of E. stigmaeumin aquaria. After the spawning period, it moves to sandy substrates in low-velocity areas of intermediate depth (Ref. 80494). Layman, S.R. and R.L.
