Appearance

The Whitecheek Tang is a dark gray to nearly black fish with a distinctive white or pale patch on the cheek (lower gill cover area). It has an oval, compressed body typical of Acanthuridae, with a scalpel-like spine on each side of the caudal peduncle characteristic of all surgeonfishes.

Diet and feeding

In captivity, provide high-quality herbivorous fare including nori sheets, spirulina-based pellets, and occasional meaty foods. Feed multiple times daily to replicate natural grazing behavior on algae and microorganisms.

Difficulty and care for the Whitecheek Tang

Moderate. The Whitecheek Tang requires stable water conditions, an appropriately sized tank (minimum 75 gallons), and a herbivore-rich diet. While hardier than some tangs, they can be territorial and are susceptible to marine ich under poor conditions.

Common health issues

Marine ich, marine velvet, bacterial infections, nutritional deficiencies

Origin and habitat

Indo-Pacific region, including the Red Sea, East Africa, Indonesia, Philippines, and extending eastward to Hawaii and the Great Barrier Reef.
