Comments: Inhabits streams and rivers, mainly over sandy bottom at medium-slow water flow.  Occasionally occurs associated with grassy marginal vegetation.  The type locality is a stretch of the Córrego Aldeia Velha, that runs through a deforested area (pasture), and is characterized by clear waters with moderate flow, less than 50 cm depth, and substratum composed predominately of sand, clay, and gravel (Ref. 96085).
