Kurzbeschreibung Morphologie | Morphometrie

This species can be distinguised from its congeners by the following set of characters: males lack the dark greenish grey bars on the anterior portion of the flank; males have transverse blue stripes on the unpaired fin wider than interspace. The body coloration of males can also be distinguished by a combination of the following characters: presence of transverse blue stripes in dorsal fin and one basal row of blue spots; most of the anal fins have transverse blue stripes; presence of blue bars on most portion of caudal fin; 8-10 light red bars between humeral region and the anterior part of the caudal peduncle; dorsal-fin origin anterior to anal-fin origin in males; and having 23 or 24 caudal-fin rays (Ref. 128003).

Maximum length based on type specimen, to be replaced with a better reference (Ref. 128003).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = No PD50 data [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00891 (0.00396 - 0.02008), b=3.14 (2.94 - 3.34), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

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

Widerstandsfähigkeit (Ref. 120179): hoch, Verdopplung der Population dauert weniger als 15 Monate. (Preliminary K or Fecundity.).

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