Maturity: L_m ? range ? - ? cm
Max length : 4.6 cm SL male/unsexed; (Ref. 13847)

Occurs from clumps of vegetation in streams with flowing waters. Sympatric with P. verruisus. Nocturnal (Ref. 13847). Recorded from fast-flowing, well shaded swamp-forest streams with acidic waters, and dense growth of submerged vegetation. Feeds on minute invertebrates and uses its dexterous and strong pelvic fins to move about (Ref. 85309).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.5 ±0.6 se; based on size and trophs of closest relatives

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
