Comments: Lives in sand-rubble fringe of rocky reefs or coral patches (Ref. 11482).  Forages on tiny crustaceans among rocks on the bottom.  When foraging over sand,  its orange spot tends to resemble sand grains and may camouflage them.  However they dart about quickly and dive for cover when approached (Ref. 28023).
