Size / Weight / Age

Maturity: L_m ? range ? - ? cm
Max length : 5.2 cm SL male/unsexed; (Ref. 57724)

Inhabits small rivers that are tannin stained, acidic, very soft and deficient of dissolved substances, with compacted clay/sand bottoms, overlain with organic detritus. Also found in large rivers with a markedly seasonal hydrological regime, substantial flood plains and water ranges from clear to turbid water, but are not tannin-stained, are less acidic, harder and carry a greater concentrations of dissolved minerals (Ref. 57724). Feeds on terrestrial and aquatic insects and preyed upon mostly by fish-eating birds and dragonfly nymphs (Ref. 57724).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5079 [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 ±0.5 se; based on size and trophs of closest relatives

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