📖 Overview

Found in sheltered habitats with rich coral growth to about 30 m depth . Observed in western New Guinea in habitats of silty dead coral reef, near the base of steep slopes 13-29 m depths; these reefs are characterised by numerous small caverns/overhangs and fish were usually seen adjacent to vertical surfaces. They appear to occupy territories or home ranges of about 2 sq. m and are often encountered solitarily, sometimes in loosely associated pairs .
