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).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.3 ±0.3 se; based on size and trophs of closest relatives

Fishing Vulnerability (Ref. 59153): Low vulnerability (15 of 100).
