Morphology | Morphometrics
soft rays: 4. Distinguished from its congeners by having the dorsal color of the head with a wedge of dark pigment on the snout and a bar from the posterior edge of the frontal to just behind the parieto-supraoccipital (the pigment may alternatively appear as dark mottling and/or the anterior marking may appear, particularly in juveniles, in the form of a dark E on the snout) (Ref. 77026).
Facultative air-breathing in the genus (Ref. 126274); Specimens from Venezuela were collected from rocks in runs (Ref. 77026). Nocturnal species; feeds on algae (Ref. 13371). Aquarium keeping: feeds on plants and roots; in groups of 5 or more individuals; minimum aquarium size 80 cm (Ref. 51539).

Bayesian length-weight: a=0.01349 (0.00730 - 0.02492), b=2.97 (2.82 - 3.12), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245
Trophic level (Ref. 69278
): 2.0 ±0.00 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 (10 of 100).
