Comments: Inhabits small rivers and creeks.  Collected at elevation from 200 to 796 m above sea level, in small headwater streams emptying into the lower portion of the Rio Pardo drainage.  Found in clear water stretches of moderate to rapid water current, 1.0-5.0 meters wide, a few centimeters to one meter deep, and with bottoms of rocks, pebbles, organic debris, and usually small amounts of sand.  Captured within, or near, the Serra Bonita Reserve Complex, a Private Natural Heritage Reserve  (R.P.P.N.), which consists of a consortium of privately owned properties, approximately 7,500 hectares and represents one of the last remnants of moist submontane forest in the region.  The area around the reserve is composed of approximately 50% primary forest and the rest is a mosaic of forests in advanced stages of recovery mixed with cabruca (cocoa trees planted under natural forest canopy) and small areas of pasture. This apparently indicates that this species inhabits streams in pristine or good condition.  Occurs syntopically with other fish species including some unidentified or possibly undescribed species of <i>Astyanax, <i>Characidium, <i>Geophagus, <i>Hypostomus, and <i>Trichomycterus (Ref. 97864).
