These fish are NOT easy to care for; very susceptable to parasites. I believe in nature they also prefer groups; it takes a huge tank to reproduce that environment. Plus, I'd say most of them have parasites by the time they're in the lfs. Just be prepared to deal with this...oh yeah, now I remember. I'm pretty sure Inland Aquatics is tank rearing these tangs. This is something I would highly recommend looking into; even if you spend extra money on the fish, you're much more likely to have success keeping them if they're tank raised.
