Comments: The area where most of the specimens were collected is a shallow creek (0.2-0.5 m depth and approximately 5 m wide) with rocky bottom, swift current, and clear water; most of the creek banks are deforested and covered with grasses.  Other fish species collected syntopically were <i>Trichomycterus</i> sp., <i>Geophagus brasiliensis</i>, <i>Neoplecostomus</i> sp., and <i>Astyanax</i> sp. (Ref. 84021).
