Épines dorsales (Total) : 16 - 23; Rayons mous dorsaux (Total) : 44 - 45. Caudal fin rays 15 and caudal fin distinctly separated from dorsal and anal fins (Ref. 97143).

Occurs in running and stagnant waters (Ref. 4833). Found in fresh and brackish waters and deltas of large rivers, common in ponds and slow flowing rivers with vegetation in plains (Ref. 41236).

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=0.00324 (0.00187 - 0.00559), b=2.99 (2.84 - 3.14), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).

Niveau trophique (Ref. 69278): 3.1 ±0.33 se; based on food items.

Résilience (Ref. 120179): Milieu, temps minimum de doublement de population : 1,4 à 4,4 années (Fec = 250).

Fishing Vulnerability (Ref. 59153): Moderate to high vulnerability (45 of 100).
