Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 17 - 19; Dorsal soft rays (total): 8 - 10; Anal spines: 3; Anal soft rays: 9 - 10; Vertebrae: 31 - 32.

Found in rather slow running water, in a section bordered with dense vegetation and in a small shallow stony brook with rather swift water; seems to be more common in fast flowing water between the stones; detritus eater; female mouthbrooder (Ref. 28906).

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

Probably a female mouthbrooder as several preserved specimens with eggs or fry in the mouth appeared to be females.

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (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).
