Short description
Identification keys | Morphology | Morphometrics
Dorsal spines (total): 7; Dorsal soft rays (total): 10; Anal spines: 1; Anal soft rays: 9 - 10. Distinguished by the following diagnostic characters: dorsal-fin rays VI-I,10; anal-fin rays I,10 (rarely 9); pectoral-fin rays 18 (occasionally 19); dentition sexually dimorphic, male teeth in upper jaw tridentic anteriorly, conical laterally; females lacking conical, canine-like teeth in both jaws; genital region without bilobed structures; both male and female with ctenoid scales on body, but those of male with stronger ctenii; female with extensive covering of cycloid scales on anterior part of body; sexual dichromatism well developed, males bright blue over much of body with ventral half of head red and broad reddish bar below second dorsal fin; dorsal and anal fins red with broad pale margins; female mainly semi-translucent tan with poorly defined brown stripe on lower side (Ref. 77028).
Occurs in mountainous terrain in cool, clear and fast flowing streams at elevations from about 100 to at least 600 m. Collected at depth ranging between approximately 0.5 and 1.3 m. Usually observed resting on the bottom attached to rock surfaces by their pelvic sucker (Ref. 77028).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 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).
