Short description Morfología | Morfometría

Espinas dorsales (total): 12 - 14; Radios blandos dorsales (total): 5-6; Espinas anales 11-13; Radios blandos anales: 8 - 10. Differs from its congeners by the following unique combination of characters: 12-13 spines in dorsal fin; 11-13 spines in anal fin; 8-10 segmented rays in anal fin; in live males, dorsal, anal and caudal fins with a narrow bluish margin and a black subdistal band bordered proximally by a bluish iridescent band, sometimes turning to reddish posteriorly; proximal part of dorsal and anal fins from dark red to black; proximal part of caudal fin red, darker in basal area; pelvic fin blue, with white filament (Ref. 56232).

Facultative air-breathing (Ref. 126274); Occurs in peat swamps (Ref. 56232).

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=0.00389 (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).

Nivel trófico (Ref. 69278): 3.1 ±0.4 se; based on size and trophs of closest relatives

Resiliencia (Ref. 120179): Alto, población duplicada en un tiempo mínimo inferior a 15 meses (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
