Short description Morfologi | Morfometri

Taggstrålar i ryggfenan (totalt): 8; Mjukstrålar i ryggfenan (totalt): 12-14; Taggstrålar i analfenan 3; Mjukstrålar i analfenan: 11. Color pattern remains similar with growth with terminal males becoming gaudier than primary males (Ref. 37816). Pale green with 6 dark bars, last two as saddles over the tail. Head with pink bands radiating from eye in large adults (Ref. 48636).

Biologi     Ordlista (t.ex. epibenthic)
