Description:

Dorsal spines: 13; Dorsal rays: 12-13; Anal spines: 2; Anal rays: 11-13.

Moderately-full bodied to slender damselfish.

Juveniles are a brilliant blue becoming dull bluish grey with growth.


Size:

Maturity: Lm unknown. Range unknown. Max Length: 11.5 cm TL.


Habitat and Ecology:

Adults occur among rubble or consolidated reef rock of exposed intertidal reef flats and sandy beaches, subject to mild surge. Also near freshwater run-offs. They occur in small groups. Feed mainly on benthic algae. Oviparous, distinct pairing during breeding. Eggs are demersal and adhere to the substrate. Males guard and aerate the eggs. Specimens photo’d here were observed in shallow sandy substrate rockpools, adjacent to a freshwater outlet.


Fishery Status:

This species is not protected or subject to fishery regulations. It is not caught in the artisanal fishery.
