This species is omnivorous, that feeds mainly on seeds, as well as terrestrial and aquatic insects. Inhabits streams and ponds between 1 and 100 m asl, in waters ranging from stagnant to swift current at temperatures ranging from 21 to 32 °C. It is usually found in pools and backwaters, where it usually hides among roots, or in caves and undercuts (Ref. 122421).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = No PD50 data [Uniqueness, from 0.5 = low to 2.0 = high].

Trophic level (Ref. 69278): 2.8 ±0.4 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
