Description
The harlequin tuskfish grows to a length of 30 cm (12 in).[2] It is a brightly colored marine fish with shades of blue, green, and orange. It has sharp blue teeth. The specimens found in Australia generally have brighter coloration.
Diet
The harlequin tuskfish is a carnivore, eating mostly benthic invertebrates such as echinoderms, crustaceans, molluscs, and worms.[2]
Distribution and habitat
The species is anti-equatorial. In the northern hemisphere, it ranges from Okinawa in southern Japan to the northern Philippines. In the southern hemisphere, its range includes Papua New Guinea, the Queensland coast of Australia, Lord Howe Island and New Caledonia.[3] This species inhabits reefs at depths from 5 to 35 m (16 to 115 ft).[2]

The harlequin tuskfish is a moderately difficult fish to maintain in captivity. Juveniles can be shy and easily bullied by aggressive tankmates, while adults will be quite aggressive.[4] At a minimum, they should be kept in a 120-gallon tank for a single specimen. They will accept frozen and meaty foods such as brine shrimp, mysis, and shellfish. It is a semi-aggressive fish and ideal tankmates would include angels, tangs, and small triggerfish. However, it will not tolerate its own kind, so there should be only one specimen per tank. They are not reef-safe. Although they will typically not nip at corals or sessile invertebrates, they will attack and consume crabs, hermit crabs, snails, and shrimp.[5]
A reef temperature of 25–28 °C (77–82 °F) is ideal for maintaining the harlequin tuskfish.[2]
