Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 7.6 cm TL male/unsexed; (Ref. 38376)
Distinguished from congeners from the Orinoco and Lake Maracaibo basins by having two or three multicuspid teeth on maxilla and four or fewer smaller lateral teeth present on dentary (Ref. 86277).
Feeds on benthic aquatic invertebrates, as well as terrestrial invertebrates which fall into the water, such as ants, wasps and bees (Ref. 26543).

= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01862 (0.00963 - 0.03599), b=2.91 (2.75 - 3.07), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.3 ±0.44 se; based on food items.
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (10 of 100) .
