Comments: Found in rocky substrates.  Restricted to places with large, very steeply sloping boulders, where it inhabits the immediately inshore slope between 0.5 and at least 5 m water depth and lives in crevices between boulders, including rock pools within emerged rocky reefs.  Stomach content analyses of males showed a seasonally variable diet of insect larvae, filamentous Cyanophyta, Bryozoa, prawns, detritus and juvenile fish (Ref. 27668).
