Comments: The type locality, Lagoa Azul, a terra-firme lake near the margin of the Rio Teles Pires, connected to it, with crystal-clear water, fed by springs at the bottom of the lake, and large stands of
  subaquatic macrophytes.  Stomach content analysis based on three specimens reveals that this species feeds mostly on vegetal matter (macrophyte fragments, unicellular and filamentous algae), and a smaller proportion of other organisms (testate amoebae, Cladocera, aquatic Hemiptera, Chironomidae larvae, unidentified invertebrate eggs).  Observed during snorkeling sessions to browse on the periphyton growing on the surface of large submerged macrophytes leaves (Nymphaeaceae).  Occurs syntopically at Lagoa Azul with other characids including <i>Thayeria sp., <i>Hemigrammus sp., <i>Moenkhausia ceros, <i>M. cotinho, <i>M. colletti, and <i>M. cf. lepidura, as well as several cichlids, anostomids, poeciliids, and stingrays (Ref. 94770).
