Comments: Found only in clear-water terra firme streams, i.e., streams dissecting the uplands, above the periodically flooded igapó forest, as the Igarapé Socó Barroso, the type locality.  These streams have width ranging from 0.80 to 20 m, moderate water current (0.1-0.7 m/s), clear,
  sandy bottom with pebbles, mud, leaf litter, and submerged logs, often also presenting aquatic macrophytes, pH ranging from 5.8 to 7.44, and water temperature ranging from 24.9° to 29.1°C.  Ripe oocytes were observed in females collected in March and August (Ref. 97524).
