Short description Bestämningsnycklar | Morfologi | Morfometri
Opercular ocellus present.
Obligate air-breathing (Ref. 126274); Inhabits swamps and creeks with little current (Ref. 12225), as well as in flooded savannas (Ref. 27188). Regularly goes to the surface of the water to breathe. Can survive long periods out of the water. This behavior of breathing air at the surface makes the fish vulnerable to predation by electric eels (Ref. 27188). Is a predaceous omnivore of open waters. Feeds on aquatic invertebrates and to lesser degree, on fish. Specimens measuring 16 cm were found to be mature (Ref. 12225).

Estimates based on models
Phylogenetic diversity index (Ref. 82804): PD50 = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01023 (0.00643 - 0.01629), b=3.14 (3.00 - 3.28), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trofisk nivå (Ref. 69278): 3.4 ±0.49 se; based on food items.
Resiliens (Ref. 120179): Hög, lägsta populationsfördubblingstid mindre än 15 månader (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153): Low vulnerability (25 of 100).
