Ecology

Habitat

Habitat and Ecology

Habitat and Ecology
This is a solitary species inhabiting fringing reefs near coral heads from 1-20 m depth (Lieske and Myers 1994). It was reported to be a mimic of the goatfish Parupeneus macronemus, changing colour when swimming close to the goatfish and this appears to help O. mentalisto approach unwary prey (Randall 2005).
