Rather rare, confined to the deeper and slow-moving parts of large rivers together with some Loricaria and Potamotrygon. Its body shape and color pattern are perfectly adapted to the muddy bottom where they stay (Ref. 35381). Feeds on benthic organisms and fish. The position of the eyes and the shape of the mouth of this piscivorous fish give to its stalking mode of hunting (Ref. 35381).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00676 (0.00575 - 0.00794), b=3.12 (3.07 - 3.17), in cm total length, based on LWR estimates for this species (Ref.
93245).
Nivel trófico (Ref.
69278): 4.5 ±0.80 se; based on food items.
Generation time: 4.9 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
Resiliencia (Ref.
