Comments: Appears to be restricted to forest streams, with a preference for fast-flowing, cooler, and crystal-clear, acid to neutral water (Ref. 75695).  A reddish morph of this species was collected in a small clearwater igarapé, about 1 meter wide and approximately 30 cm deep, with fine white sandy bottom, no submerged vegetation, rocks or pebbles, a pH of 4.8 at a temperature close to 29°C (Ref. 75695).
