Remarques The species lives in streams, occuring in semi-lentic and lotic shallow areas (up to 1 m deep) with riparian vegetation composed by trees and shrubs. The species was collected syntopically with Aspidoras albater, Astyanax sp., Characidium stigmosum, Corumbataia veadeiros, and Trichomycterus sp. Stomach contents of five specimens were mainly composed by Diptera (pupae) and allochthonous insects, but it was also found authochthonous insects and digested vegetal matter in a lesser amount (Ref. 84464).
