The type locality of this species in Quebrada Pachija, was described as an open-gallery, high flow stream with a flow of 0.748 m/s, a mean stream depth of 0.397 ± 0.059 m, and a mean stream width of 19.1 ± 1.0 m. It was also observed t in the fastest flowing water sampled; where most adult specimens were captured from a single rocky rapids. These collections
also yielded numerous fry and small juveniles from within floating debris along the fast-flowing
edges of the Río Manu, however, identification of these samples still to be confirmed (Ref. 84053).
