Environment: milieu / climate zone / depth range / distribution range
Ecology
Freshwater; benthopelagic; pH range: 7.0 - ? ; dH range: 10 - ?. Tropical; 25°C - 30°C (Ref. 2059)
South America: Atlantic coast drainages of Suriname, French Guiana, Guyana, Venezuela and Trinidad.
Size / Weight / Age
Maturity: Lm ? range ? - ? cm
Max length : 20.0 cm SL male/unsexed; (Ref. 36377)
Often found in creeks, but sometimes captured in rivers, specially during the dry season. A formidable predator; it consumes essentially aquatic insects, fish and plant material. Not very popular among aquarists because of its aggressive behavior (Ref. 27188).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01288 (0.00746 - 0.02224), b=3.07 (2.92 - 3.22), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref.
93245).
Trophic level (Ref.
69278): 3.3 ±0.49 se; based on food items.
Resilience (Ref.
120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (14 of 100).
