Great question! Anyone in the group familiar with Australian Harlequin Tuskfish? I would like info, too.

Usually any sea creature with the name 'Harlequin' included is indicative of pretty coloration. I was privileged to see a Harlequin Shrimp at a LFS, and it was BEAUTIFUL. (Unfortunately, the only food this precious shrimp is known to eat is starfish.)

Harlequin Tuskfish
Lienardella fasciata

Tuskfish are members of the Labridae (Wrasse) family. There are over 20 species found throughout the Indo-Pacific, some growing to over 3 feet in length. Harelquin Tusks are found in the Western Pacific from Australia to Japan.

This fish is named its four very prominent tusk-like teeth that protrude visibly from its jaws. These teeth are ideal for feeding on its favorites foods - crustacea and mussels. Appearance to the contrary, the Harlequin Tusk is a peaceful tankmate when kept with similarly sized fish. It should not be kept with fish that will fit in its mouth.

As with many fish, juvenile coloring (left) is noticeably different from adults. However, the sexes are virtually indistinguishable. Any quality frozen food containing clams, mussels and squid will provide excellent nutrition. Like most wrasses, they sleep on the bottom and should be provided with a rocky retreat. These very hardy fish make a spectacular addition to a display aquarium.

Common Name: Harlequin Tuskfish

Scientific Name: Choerodon fasciatus

Family: Labridae (Wrasse)

Distribution in Australia: North-eastern coast of Australia from Coffs Harbour, NSW to Cape York Peninsula, Qld.

Habitat: Coastal species that occupies lagoons located in outer reef areas. Adults may form small loose groups in cave zones or around overhangs located near reef slopes. Juveniles prefer to remain alone near reef walls that drop off to channels.

Size/Age: Up to 250 mm in length.

Adaptations:

Teeth: Harlequin Tuskfish have a mouth filled with blue teeth. To warn other fish, when it feels threatened, the Harlequin Tuskfishís teeth change colour from blue to pink.


Warning colours: The colourful patterned body also warns predators that their flesh may be inedible, bad-tasting or poisonous.


Summary:

Body colour: Adults are easily identified by orange/red stripes over the head and body. Towards the yellow tail, the back area is dark blue to purple. Juveniles have small black spots on the fins.


Locomotion: Like many of the fish species inhabiting coral reefs, their pectoral fins move in a flapping motion, and are used for forward movement. There is little propulsion by the tail as found in pelagic, schooling fish. The tail is used for steering, which is very important when navigating through tight crevices and between corals and caves.


Further Information:

Male or female? The Harlequin Tuskfish belong to the Wrasse family, where the young all hatch as females. Social groups develop as they mature into adults. The most dominant female of this group goes through physiological changes, from a female to a male. He (she) then roosts over a harem of females. When he dies or leaves the group, the next most dominant female changes sex into a male.
From what I have read they are not exactly reef safe as they will eat shrimp or other crustaceans that you might have in the tank.
