Environment: milieu / climate zone / depth range / distribution range
Freshwater; benthopelagic; pH range: 5.3 - 5.7; dH range: 2 - 3; depth range - m (Ref. ), usually - m (Ref. ). Tropical; 23°C - 26°C (Ref. 13371)

Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 12.0 cm SL male/unsexed; (Ref. 27732)
soft rays: 9 - 10;
Vertebrae: 29 - 30. A dark grey midlateral stripe, more intense posteriorly, not extending onto the caudal fin; dorsal-fin origin closer to the eye than to the caudal-fin base; 3 scale rows between the lateral line and the midventral row; caudal fin usually with a black posterior margin (Ref. 27732).
Occurs in a variety of habitats, but seems to prefer large rivers with slow current (Ref. 27732). Common along shores in large rivers (Ref. 56749). Found at or near the surface in clear waters of rivers and streams. Generally prefers a depth of about 5 m. Feeds mainly on exogenous insects, some small crustaceans and algae (Ref. 12693).

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00851 (0.00376 - 0.01926), b=3.07 (2.87 - 3.27), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 2.9 ±0.36 se; based on food items.
Generation time: 2.9 ( na - na) years. Estimated as median ln(3)/K based on 2 growth studies.
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (K=0.38-0.69).
Vulnerability (Ref. 59153
): Low vulnerability (21 of 100) .
