Habitat and Ecology:

Inhabits inshore and offshore coral or rocky reefs (depth 1-20m). Also utilises shallow coastal reef flats or crests particularly where lots of tall soft corals or hydroid colonies are present. Feeds on zooplankton, benthic invertebrates, and algae and aggregates high in the water column. Oviparous, distinct pairing during breeding. Eggs are demersal and adhere to the substrate. Males guard and aerate eggs, and maintain a nest site in which multiple females may deposit their eggs.


Fishery Status:

This species is not protected or subject to fishery regulations. It is caught in the fish trap fishery, but is an uncommon component of the catch, possibly due to usually being released by fishers when caught.
