Maturity: Lm ?  range ? - ? cm
Max length : 6.0 cm TL male/unsexed; (Ref. 36880); 10.5 cm TL (female)
Found in waters of all current velocities, but are more abundant in slack waters. Very large individuals (up to 105 cm) are found in brackish water, while smaller individuals occur in brooks to an elevation of 1220 m. Inhabit swamps, brooks and in shallow waters of large rivers, generally found near the substratum browsing on detritus, ooze and filamentous algae, reproduces throughout the year, but with a peak in juvenile abundance in August (Ref. 36880).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01479 (0.00834 - 0.02624), b=3.25 (3.10 - 3.40), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref.
93245).
Trophic level (Ref.
69278): 2.5 ±0.3 se; based on size and trophs of closest relatives
Resilience (Ref.
120179): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
