South America: Orinoco River basin. Reported from Argentina (Ref. 9086). Introduced and have established in Taiwan, mainland USA and Hawaii (Refs. 5723, 44091, 58503).

Length at first maturity / Taille / Poids / Âge

Maturity: L_m 32.5, range 25 - 40 cm
Max length : 50.0 cm TL mâle / non sexé; (Ref. 2059)

Facultative air-breathing (Ref. 126274); Occurs in streams and lakes (Ref. 44091) and in weedy, mud-bottomed canals (Ref. 5723). Benthic (Ref. 58302). Nocturnal, feeds on algae (Ref. 13371), but will also feed on worms, insect larvae, and other bottom-dwelling aquatic animals (Ref. 44091). Spawning period peaks once a year (Ref. 56986). Reproductive behavior includes digging of burrows for egg laying (Ref. 82067). May exhibit male parental care (Ref. 56986).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.02455 (0.01270 - 0.04744), b=2.91 (2.75 - 3.07), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).

Niveau trophique (Ref. 69278): 2.2 ±0.12 se; based on food items.

Résilience (Ref. 120179): Milieu, temps minimum de doublement de population : 1,4 à 4,4 années (tm=1; Fec = 1,983).

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (40 of 100).
