Morphology | Morphometrics
Body with a black band along the body; back greenish brown, sides yellowish and belly pearl white. A band bordered above and below by iridescent greenish yellow stripes present from the tip of the snout to the middle of the tail. Dorsal fin with some dark spots near the base; caudal fin transparent except fo the lateral band extending onto the middle rays; paired fins and anal fin transparent. Both adults and juveniles have the same coloration (Ref. 36880).
Collected from rivers, creeks and ditches between 5 and 100 m elevation in stagnant waters or waters of low to moderate current velocity; at temperatures of 25-30°C. Abundant among undergrowth or vegetation where it feeds on aquatic insects (Ref. 36880).

Estimates based on models
Phylogenetic diversity index (Ref. 82804
= 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00411 - 0.02433), b=3.06 (2.85 - 3.27), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.2 ±0.40 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).
