Short description Morphology | Morphometrics

Dorsal soft rays (total): 8-9; Anal soft rays: 13 - 15; Vertebrae: 31 - 35. Differs from other species of the genus by a combination of characters including dorsal and anal fin ray counts, number of scales in lateral and transverse series, by the lack of the supracaudal spot at all ages in both sexes, a short base dorsal fin, a yellow color background on body, a red colored sub-distal area on anal fin in male, with a yellow one in female, and a dark margin on caudal fin (Ref. 78216).

Biology     Glossary (e.g. epibenthic)

Occurs in small groups in small mountainous rivers and marshes (Ref. 78216).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00661 (0.00311 - 0.01404), b=3.09 (2.91 - 3.27), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.3   ±0.4 se; based on size and trophs of closest relatives
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).
