Short description Chiavi di identificazione | Morfologia | Morfometria

Raggi dorsali molli (totale) : 16 - 24; Raggi anali molli: 19 - 24; Vertebre: 28 - 30. Caudal peduncle of female with black spots. Male's anal fin with gray to black distal stripe, iridescent dots restricted to posterior portion of the fin, anterior part pink and posterior yellow; basihyal broad, 70-95% in length; and, second pharyngobranchial teeth, 5-10. Dorsal-fin rays 22-24 in male, 16-18 in female; anal-fin rays 23-24 in male, 19-21 in female; caudal-fin rays 24-26, caudal fin subtruncate in male, rounded in female. Possess minute pectoral-fin contact organs, and no black blotches and round brilliant spots on anterobasal part of dorsal fin of male (Ref. 49550).

Found in temporary pools (Ref. 89836). Bottom spawner, 3 months. Is difficult to maintain in aquarium (Ref. 27139).

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=0.01995 (0.00906 - 0.04395), b=3.01 (2.83 - 3.19), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.3 ±0.4 se; based on size and trophs of closest relatives

Resilienza (Ref. 120179): Alto, tempo minimo di raddoppiamento della popolazione meno di 15 mesi (Preliminary K or Fecundity.).

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

Price category (Ref. 80766): Unknown.
