Remarks | This occasionally schooling species inhabits lagoon and seaward reefs: juveniles on reef flats, adults tend to occur around rocky or coralline areas of high vertical relief. Feeds on crustaceans at daytime and on fishes and crab larvae at night. Also feeds on worms (Ref. 6113). Uses its sensory chin barbels to probe the sea floor for hidden prey; preys after dark on such diurnal fishes as blennies and damselfishes, probably taking them from where they shelter themselves at night (Ref. 13550). |
