Choerodon fasciatus (Harlequin Tuskfish)

The Harlequin Tuskfish is a striking and personality-filled member of the wrasse family that often becomes a fast favorite in larger marine aquariums. Known for their bold coloration and outgoing behavior, these fish are interactive, confident swimmers that bring constant movement and character to the tank.

The individuals currently available are juveniles, but this species grows to an adult size of up to 10 inches, making a large aquarium (150 gallons or more long-term) a requirement. They prefer systems with ample rockwork and rubble zones, which allow for natural foraging behavior and provide a sense of security.

These juveniles are bred in Bali, with parent stock originating from Australian lines, which are prized for their deeper, brighter red coloration compared to other regional variants.

The Harlequin Tuskfish is not totally reef safe. As it matures, it will prey on clean-up crew members, ornamental invertebrates, and potentially very small fish. Adults are typically semi-aggressive and are best housed in fish-only aquariums with similarly sized, robust tankmates.

As they mature, Harlequin Tuskfish develop their iconic appearance—bold vertical red-orange and white striping, subtle blue accents, and large, vibrant blue “tusk” teeth used to crush small invertebrates.

Best kept in:

• Large fish-only aquariums (150G+ recommended)

• Systems with substantial rockwork and rubble

• Tanks with similarly sized, semi-aggressive tankmates

This species is an excellent choice for aquarists looking for a show-stopping centerpiece fish with intelligence, personality, and unmistakable presence—when given the space and setup it deserves.
