At my lfs. Not sure what kind, but a very impressive/expensive fish. Lfs recieved him for free when a customers tank broke down, but the manager will not sell him for anything less than $2,000.
Sorry for all the pics, got a little carried away lol.
Wow!! Can't narrow down the species. I've only seen that color combo in Aulacocephalus temminckii, the goldstripe soapfish. But, the yellow pectorals aren't part of the species coloration.
