Inhabits slow and shallow waters of rivers of plains and estuaries; never available above an altitude of 366 m. Also found in canals, streams, beels, ponds and inundated fields (Ref. 1479). Has been placed into aquaria and kept by hobbyists; it stays on the bottom and spawns in the upper water-level. The more slender and generally smaller males pursue the female in courtship; several males may join in.

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=0.00427 (0.00333 - 0.00547), b=3.00 (2.94 - 3.06), in cm total length, based on LWR estimates for this species (Ref. 93245).
栄養段階 (Ref. 69278): 3.5 ±0.51 se; based on food items.
回復力 (Ref. 120179): 高い, １５か月以下の倍増期間の最小個体群 (K=1.0-1.7).
Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
Nutrients (Ref. 124155): Calcium = 354 [225, 712] mg/100g; Iron = 2.41 [1.44, 4.14] mg/100g; Protein = 17.6 [16.2, 18.9] %; Omega3 = 0.173 [0.085, 0.348] g/100g; Selenium = 52.6 [24.3, 111.0] μg/100g; VitaminA = 31.9 [13.8, 72.4] μg/100g; Zinc = 1.43 [1.06, 1.97] mg/100g (wet weight); based on nutrient studies.
