South America: Coastal rivers of Suriname and French Guiana.
Size / Weight / Age
Gregarious. Forms schools of about a dozen individuals. Frequently occurs upstream in counter current zones. Is an omnivore with a tendency to feed on insects (Ref. 12225). Crepuscular. Appreciated by aquarist notably for its tendency to live in groups and for it habit of swimming with the body oriented upwards. Reproduces in captivity. The spawned eggs, which are fixed to vegetal substrate, do not receive parental care (Ref. 27188).

Estimates based on models
Phylogenetic diversity index (Ref. 82805): PD50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00603 (0.00259 - 0.01401), b=3.09 (2.89 - 3.29), in cm total length, based on LWR estimates for this Subfamily-BS (Ref. 93245).
Trophic level (Ref. 69278): 3.2 ±0.40 se; based on food items.
