Comments: Collected from a fast flowing, tea-colored water running on a bedrock bottom, and a fair amount of preserved marginal vegetation. Captured specimens in places 0.2-1.7 m deep and 3-16 m wide. Individuals are very abundant, and most were hand-caught among rocks and inside cracks and crevices of the bedrock. Associated species caught are <i>Euryochus thysanos, Astyanax aff. fasciatus</i>, and unidentified species of <i>Characidium</i> and <i>Trichomycterus</i> (Ref. 119415).
