Has anyone on the board ever successfully kept an achilles tang? I think these fish are awesome, and seem to be farely rare in the pet stores. I am considering a new fish, and the achilles is one that I am looking at. After doing some reading about the species, it seems to me that they may be difficult to keep. If there is anyone out there that has one or has had experience with them, please help me out. The las thing I want to do is spend $65 on a fish that is going to die in a week.
