Size: To 31 cm

Family: Acanthuridae, the family of surgeonfishes, tangs, and unicornfishes. Around 86 species in total, which live in tropical waters, usually around coral reefs.

Weight: Adults typically weigh around 600 grams.

Distribution: The Blue Tang can be found throughout the Indo-Pacific. It is seen in the reefs of the Philippines, Indonesia, Japan, the Great Barrier Reef of Australia, New Caledonia, Samoa, East Africa, and Sri Lanka. In Australian waters it's found along the QLD coast, and as south as mid-NSW.

Status: Least concern

Habitat: Coral reefs, the Blue Tang hides among branching coral.

Danger: The Blue Tang can cause ciguatera poisoning if consumed by humans. Handling the tang risks the chances of being badly cut by the caudal spine. These spines, on both sides of the caudal peduncle, are extended from the body when the fish becomes excited. The quick, thrashing sideways motion of the tail can produce deep wounds that result in swelling and discoloration, posing a risk of infection.
