South of Carnarvon, Shark Bay, Western Australia, around the tropical north to Moreton Bay, Queensland. tropical, Indo-west Pacific. Records of this species from southern Queensland may be misidentifications of the Smooth Razorfish, Centriscus cristatus.

Elsewhere the species is widespread in the tropical Indo-West Pacific, from the Red Sea and Arabian Gulf to New Guinea, northwards to southern Japan and southwards to eastern Australia. 

Found over fine sediments like mud or silty sand and known to associate with sea grasses, branching corals, seawhip gardens and black coral

Inhabits muddy and silty areas in near coastal reefs, often in association with seagrass beds, branching corals, seawhips and black corals to depths of at least 72 m (in Australia). Adults may form large schools above corals and seawhips.
