The orange spotted filefish or harlequin filefish, Oxymonacanthus longirostris, is a filefish in the family Monacanthidae found on coral reefs in the Indo-Pacific Oceans. The orangespotted filefish is a different species and refers to Cantherhines pullus.[1]

The orange spotted filefish is pale blue with about eight longitudinal rows of orange-yellow patches. In the wild it feeds almost exclusively on Acropora polyps.[2]

In the aquarium[edit]

It is often offered for sale in the aquarium trade, but few specimens survive long in captivity.[3] It is difficult to maintain in an aquarium unless it is provided with live corals. The fish must be kept in a species-specific tank, or a tank with very passive tankmates such as seahorses or pipefish.
