Powder Brown Tang Profile

Scientific Name:

Acanthurus japonicus (Fowler, 1946).

Other Common Names:

Powder Brown Surgeonfish.

Distribution:

Western Pacific.

Average Size:

8.3 inches (21 cm).

Characteristics and Compatibility:

A popular fish, but one that requires much attention, the Powder Brown Tang is known to be delicate to care for, and hard to acclimate. It is highly susceptible to contracting ich, and can have problems with HLLE. It can be aggressive towards other surgeonfishes, particularly those of the same shape and color. It is best housed as the only tang present in an aquarium, with the possible exception of a larger system. Although the similar Goldrim or Whitecheek Tang (Acanthurus nigricans) is also delicate, it is somewhat more durable.

Diet and Feeding:

Primarily a herbivore that will graze on filamentous micro and some types of smaller fleshy macroalgae. Should be fed a diet of frozen and dried fares suitable for herbivores that contain marine algae and Spirulina (blue-green algae). Zucchini, broccoli, leaf lettuce, and nori (dried seaweed) can be offered to supplement its diet. Should be fed at least 3 times a day.

Habitat:

A somewhat shy fish, the Powder Brown Tang should be provided with ample room to move around and lots of places to hide. Does best in a well established aquarium with an ample growth of algae present to graze on at its leisure.

Suggested Minimum Tank Size:

75 gallons (284 L).

Reef Tank Suitability:

Considered safe, but an individual may pick at large polyped stony corals if not well fed.

Guide Notes:

It sounds silly, but this a fish that seems to break out with ich if you even look at it the wrong way. Often specimens we have kept have not readily accepted foods offered. For this reason it is best to ask to see this fish eating, before you buy one.
