Adults live in freshwater rivers and streams. Young are encountered occasionally in brackish waters. This is the only mullet that ascends far inland and spends all its adult life in freshwater (Ref. 11225). Tend to be few and solitary in upper streams, but form uneven schools in larger streams at lower elevations (Ref. 11225). Oviparous, eggs are pelagic and non-adhesive (Ref. 205). Usually spawn during the rainy season (Ref. 42119). Caught and consumed by local populations in some parts of central America.

Bayesian length-weight: a=0.01148 (0.00526 - 0.02507), b=2.95 (2.77 - 3.13), based on LWR estimates for this Subfamily-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 3.4 ±0.5 se; Based on diet studies.
Resilience (Ref. 69278
): High, minimum population doubling time less than 15 months (Fec = 128,827).
Vulnerability (Ref. 59153
