Habitat Type: Freshwater
Comments: This fish occurs in various stream and river habitats; it is most abundant in rock- and sand-bottomed pools and backwaters; also in caves in Mexico (if those populations are conspecific). In Mexico, this fish occurs in river pools and fairly shallow backwaters in moderate current (Miller 2005). Habitats in Arizona include swift rapids, eddies, and pools. In New Mexico, it occurs primarily in habitats with stenothermal flows (springs) (Sublette et al. 1990); young have been observed in shallow water near overhanging bank vegetation.
