From marine depot: Also known as a "white cheek tang"
The Acanthurus nigricans grows up to 8 inches. The White Cheek Tang prefers a tank of at least 80 gallons with plenty of places to hide & swim. The Acanthurus nigricans is a herbivore and likes to eat marine algae, zucchini, brocoli, mysid shrimp, Spirulina, lettus, seaweed, sponges, and other meaty treats. The White Cheek Tang is a medium maintenance fish and may act peacefully toward other fish. Reef-safe. Filters pose a threat to the planktonic offspring. Passive fish. Acanthurus (glaucopareius) nigricans (Linnaeus 1958), the Powder Brown or Gold-Rimmed Surgeon. The corrected scientific name of this species is A. nigricans (per Randall, 1988); a revision no doubt as unpopular to some as my labeling the species as "bad". The very similar A. japonicus is a far better aquarium fish. Keep water quality high (SG 1.020 - 1.025, pH 8.1 - 8.4, Temp. 72 - 78° F). The White Cheek Tang is commonly collected from Hawaii.
