A Foxface at Sydney Aquarium.
The Foxface is recognised by its distinctive shape and colouration. It has an elongated snout and concave head profile. Adults have a diagonal black band from the dorsal fin origin, through the eye to the mouth. The breast is covered by a large black triangle. The posterior portion of the body and fins are bright yellow.
Juveniles form schools and shelter in coral. By the time the fish have reached 10cm in length, they form pairs. These pairs are believed to be maintained for life.
This species occurs widely throughout the western Pacific. In Australia it is recorded around the tropical north from Ashmore Reef, Western Australia to the Capricorn Group, Queensland.
The Foxface is classified in the family Siganidae. Fishes in this family are commonly known as rabbitfishes. This is in reference to the distinctive snout shape. Rabbitfishes have several unusual fin characteristics. The pelvic fins (glossary) have two spines separated by three soft rays. The anal fin has seven spines, more than most other bony fishes. All the dorsal, pelvic and anal spines have grooves and poison glands. A wound from any of these spines can be very painful.
One species of siganid, Siganus nebulosus (Quoy & Gaimard), has the common name "Happy Moments", a sarcastic reference to the pain endured by people who have not handled this fish with care.
