Orange Spot Filefish

(Oxymonacanthus longirostris)

Oxymonacanthus Filefish should be added to well established aquariums with plenty of room to swim. Plenty of rock work with caves and ledges should be provided for grazing and hiding. Oxymonacanthus Filefish are shy, secretive and peaceful fish that should be housed with other peaceful fish. They are slow moving fish, avoid high water flow. Oxymonacanthus Filefish are not reef safe they feed mainly on stony corals especially Acropora corals. They may also nip and consume aiptasia, small crustaceans, snails and crabs. They can be trained to eat prepared foods however coral polyps will need to be supplemented while training in order to thrive.

Orange Spot Filefish are also sometimes known as the Harlequin Filefish. Not often seen in the aquarium trade. Beautifully colored with a pale blue to gray body color with orange to yellow spots. Orange Spot Filefish can grow to almost 5".

We recommend a minimum aquarium size of 50 gallons or larger for this species.
