I believe it is a Ctenochaetus binotatus, which is in the bristletooth family. From WWM:
"One of six genera of acanthurids, Ctenochaetus comprises nine of the seventy-five or so described species of Surgeonfishes. Specialized mouths and teeth (cteno-chaetus means "comb bristle" define the genus’ members. Unlike other surgeons that have rigid, attached dentition, Ctenochaetus have movable, individual, bristle-like teeth. Coupled with a protrusible, outreaching mouth, these fishes use this unusual feeding device to sort and remove interstitial fauna, scrape soft algae, and "detritus" of nutritive value from rock and substrate. "
This does not look like any of the Acanthurus genus: http://www.wetwebmedia.com/acanthurtngs.htm

The body is to long to be in that family. I have fish in that family and they do not have a long body like this. They are much shorter and rounder shape. I looks closer to a gold rim ting but with different color variations.
