This species is brown overall, with a white band under the eye, yellow along the anal and dorsal fins bases and orange on the outer edges of these two fins. The powder brown is similar to the Gold Rim Tang (Acanthurus nigricans). Both are can be shy when introduced to the aquarium and will require suitable hiding places to refuge in if threatened. The powder brown can be finicky when it comes to adjusting to eating prepared foods, so a tank with a flourishing algae crop or live rock will ensure it gets enough to eat during the acclimation process. Like most tangs, this species can be aggressive toward surgeonfish tankmates once it acclimates, especially members of its own kind (keep only one per tank).
requires a 50 gallon or larger aquarium with a number of hiding places and plenty of room to swim.
In nature it feeds almost entirely on brown macroalgae and should be offered a wide a variety of foods including plenty of algae. Although Tangs will eat meaty foods along with the other fish in the aquarium, it is important that they are offered plenty of seaweed and algae. These are the foods that will strengthen their immune system, reduce aggression and improve their overall health. Offer dried seaweed tied to a rock or use a veggie clip, and feed at least 3 times per week. Sea Veggies, Seaweed Salad and Ocean Nutrition are all ideal products and are very easy to use.
Great reef fish, fares notably better in reef aquariums than in fish only tanks.
