Description synthétique Clés d'identification | Morphologie | Morphométrie

Épines dorsales (Total) : 3; Rayons mous dorsaux (Total) : 21 - 23; Épines anales: 3; Rayons mous anaux: 12 - 14. Females sexually dichromatic dottyback are uniformly grey, sometimes becoming yellowish or reddish on the tail (Ref. 37816).

A common but secretive species (Ref. 9710, 48635) found in holes and crevices of exposed outer reef flats and reef margins. Occurs in pairs and feeds on small crabs, isopods, and copepods (Ref. 1602). Usually most abundant in high current or surge areas. Frequently enters the aquarium fish trade and has been bred in captivity (Ref. 37748). Sometimes solitary (Ref 90102).
