Facultative air-breathing (Ref. 126274); The type locality of this species is a small stream tributary to the rio Suspiro, rio das Mortes basin; its width ranging from less than one meter to about five meters, and depth ranging from about 10 cm to nearly two meters. The species was found in shallow stretches (up to about 20 cm) with moderate current, the substrate composed by sand, fine gravel, and larger rocks, where the specimens were observed burying themselves on sandy substrate using undulatory movements of the body. This species seems to form small shoals of less than 10 individuals and was often found in syntopy with an unidentified species of Characidium (Ref. 129024).
