Care
The Whitecheek Tang is known from clear lagoons and seaward reefs, from the lower surge zone down to 67m (220ft). Here, these fish feed primarily on filamentous algae - the juveniles gregarious amongst large coral heads, and the territorial adults more solitary. This is a very delicate fish, suitable for advanced aquarists only. It is a species that is best maintained in a large, mature reef setting where there is an abundant growth of algae on the live rock, upon which the fish can constantly browse. Hostile towards its own kind and other Acanthurus species, keep only one per tank. Ensure that there are plenty of hiding places amongst the reef structure for the Whitecheek Tang to retreat into if necessary, particularly during the settling in period when it may be a little shy. Water quality must be maintained to consistently high standards, as, like some other members of this family, the Whitecheek Tang is susceptible to whitespot, which can be difficult to treat in the reef aquarium. This is an agile fish that appreciates a good amount of swimming space and a decent current. There is a very similar looking species, the Powder Brown Tang (Acanthurus japonicus), known from the Western Pacific. Both species have been sold under the Gold Rimmed Tang nametag, and so it is best to use the scientific name to avoid confusion. Interestingly, in some parts of its natural range, the Whitecheek Tang is known to hybridise with the Achilles Tang (A. achilles).
Feeding
Can be finicky. Offer a varied diet, consisting mainly of vegetable matter, in small amounts 3 times per day. Although this species will browse on algae within the aquarium, its diet must be supplemented with frozen herbivore rations, green marine flake, Spirulina (blue-green algae), Spirulina-enriched brineshrimp, cucumber, lettuce, Nori (dried seaweed) etc. It will also take small meaty frozen foods, but be sure that it is receiving enough green food to prevent HLLE. Adding a specially formulated vitamin supplement to any frozen foods will be beneficial.
Breeding
This species has not been bred in the home aquarium.
