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).
相当稀有, 局限于那比较深的与大河的缓慢移动的部份伴随着一些 Loricaria 与 Potamotrygon. 它的体型与彩色斑纹完全地被适应到泥底部在哪里它们停留。 (参考文献 35381) 吃底栖的生物与鱼。 眼的位置与这个以鱼为食的鱼的嘴巴的形状给它的猎食的秘密接近的方式。 (参考文献 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).
营养阶层 (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.
