Acanthurus leucosternon Bennett 1832, the Powder Blue Tang. I can hear some of you screaming, "this isn't a difficult fish!" "I've known people to keep the Powder Blue for years!" Most specimens don't make it. Those that are well received and cared for sometimes do live for a good long time. Two maxims for success: One to a tank, and lots of live rock with algae.

Acanthurus (glaucopareius) nigricans (Linnaeus 1958), the Powder Brown or Gold-Rimmed Surgeon (and Whitecheek Surgeon to science), Cat Tang in Hawai'i.... 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; A. nigricans rarely lives for more than a few months in captivity, often, oh joy, bringing in parasitic Protozoan disease to take the rest of your fish livestock with them.



Acanthurus japonicus (Fowler 1946), the Japanese or White-Faced Surgeonfish; is also sold as a/the Gold-Rimmed or Powder-Brown Surgeon, confusing it with A. glaucopareius (nigricans) (see below). To further confuse matters, this fish is also sold as the Whitecheek Surgeon/Tang in the aquarium trade...A. japonicus has a much larger white eye patch. Ranges from the Philippines to Japan and is relatively hardy. Aq. pic.
