Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 30.0 cm SL male/unsexed; (Ref. 30857)
soft rays: 21 - 25. Preserved color dark greenish or bluish dorsally, yellowish or reddish brown ventrally; an inconspicuous spot behind corner of mouth; yellow spots on underside of depressed head occasionally. Pectorals about as long as head behind eyes. Large scales on top of head. Dorsal fin extends beyond tip of anal. Young specimens have a red lateral band from snout to caudal.
Obligate air-breathing (Ref. 126274); Inhabits medium to large rivers (Ref. 12975). Occurs in shaded forest streams with sluggish, acidic water and submerged roots/leaf litter substrates. Appears to be mainly nocturnal and feeds on small animals (Ref. 85309). Preys on fish (Ref. 12693).

Estimates based on models
Phylogenetic diversity index (Ref. 82804
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00871 (0.00388 - 0.01954), b=2.97 (2.79 - 3.15), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245
Trophic level (Ref. 69278
): 4.2 ±0.73 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 to moderate vulnerability (27 of 100).
