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.
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.
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.
SIZE IS 2-4 INCHES
