Orange spotted filefish (Oxymonacanthus longirostris)

The orange spotted filefish is a filefish in the family Monacanthidae found on coral reefs in the Indo-Pacific Oceans. It is pale blue with about eight longitudinal rows of orange-yellow patches. In the wild it feeds almost exclusively on Acropora polyps. Orange spotted filefish absorb and use chemicals in the Acropora coral they eat to take on its smell, which cloaks them from natural predators like cod.
