Facultative air-breathing in the genus (Ref. 126274); Found in backwaters of rivers, small creeks, swamps, and lily lagoons, usually among thick aquatic vegetation over soft mud bottoms. Females lay about 30 eggs (2 millimeters in diameter) on the ceiling of overhanging rocks or crevices. These are guarded and fanned by males until hatching, which takes about 8 days (Ref. 44894).

Estimates based on models

Fylogenetische diversiteitsindex (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00955 (0.00432 - 0.02113), b=3.05 (2.85 - 3.25), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trofisch niveau (Ref. 69278):  3.2   ±0.6 se; based on size and trophs of closest relatives
Weerstandsvermogen (Ref. 120179):  Hoog, minimale populatieverdubbelingstijd minder dan 15 maanden (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
