Comments: Occurs in tributaries of the upper Ribeirão Caraça as well as in the main course of Ribeirão Caraça.  These tributaries are blackwater rivers with translucent and fast flowing water and bottom consisting of very large rocks sparsely covered by iron-ore pebbles and gravel. These rocks are covered by a thin layer of periphyton and green algae.  Found in medium-sized streams, relatively shallow (0.5 to 1.5 m deep). Small specimens and juveniles were collected in stretches of relative-slow water currents, associated with loose stones and pebbles deposits.  Food items found in the guts of 2 specimens (3.91-8.26 cm SL) were mainly filamentous algae.  Collected together with <i>Oligosarcus</i>	 sp. and <i>Hoplias cf. malabaricus</i>	 in stretches of slow-water pools (Ref. 91754).
