Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 7; Dorsal soft rays (total): 9; Anal spines: 1; Anal soft rays: 10. This species is characterized by the following: pectoral rays 14-15; second dorsal fin with 9 segmented rays; premaxillary teeth 39-44; predorsal midline with 4-12 scales; males with more and larger symphyseal teeth than females (3-4 vs. 1); transverse scales in forward series 7-8, in backward series 8-9; typical color of males, body with longitudinal bright line divided in 3 colors (re, yellow, green from back to belly) on the flanks up to the head, on the cheeks, to the nose; lower part of head dark green to black; belly greyish brown on the back; females greyish to brownish (Ref. 72456).

Occurs in clear and calm streams, sandy or slightly rocky bottom and large pools. Found on the bottom of the river and observed from 5-10 m high in altitude (Ref. 72456).

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=0.01122 (0.00514 - 0.02450), b=3.04 (2.87 - 3.21), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

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).
