Harlequin Filefish - Oxymonacanthus longirostris
The Harlequin Filefish (Oxymonacanthus longirostris) is truly unique. This beautiful, but shy filefish is a light shade of green with orange spots. It has an elongated nose and body. In the wild, they eat only Acropora coral polyps. Although attractive, this is one of the more difficult filefish to keep in home aquariums due to their specialized diet.
Filefish are related to the "Triggerfish" common to the aquarium trade but are generally much more docile and peaceful in nature. Although they are compatible with most fish of a similar temperament, they are generally not Reef Safe and will pick at corals, polyps, crabs and other invertebrates. They are best kept in a peaceful, fish-only community aquarium.
Some filefish may be tricky to acclimate to an aquarium diet. Most will accept meaty foods like plankton, clams, brine shrimp, mysis shrimp and similar items. Filefish have small mouths designed for picking food items from small crevices and they cannot eat large items. They may still pick at or attempt to eat crustaceans like shrimp however and may pick at or eat some corals and polyps.
