Lives mainly in small streams and waterholes in clear to moderately turbid water. Occurs over rocky or gravel bottoms or in well-vegetated areas, frequently around submerged logs and branches. Occurs at temperature and pH ranging from 22°-30° C and 5.2-7.0 respectively. Inhabits small creeks and waterholes in semi-rainforest or open grassland areas. Occasionally abundant in partly stagnant waterholes with leaf litter bottoms during the dry season. Species is easy to maintain and thrives in captivity (Ref. 44894).

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=0.01122 (0.00514 - 0.02450), b=3.04 (2.87 - 3.21), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 2.9 ±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).

Price category (Ref. 80766): Unknown.
