SPS in general require a heavy flow, clean water, and bright light. The coral you were told you have is a "designer" coral, offered by a coral farmer legend, Steve Tyree. He runs a company called http://www.dynamicecomorphology.com">www.dynamicecomorphology.com</a>, or [IMG]http://www.reeffarmers.com">www.reeffarmers.com</a>. There is a waiting list for some of his frags til 2010 or later. Its craziness.
Not to burst your bubble, but I dont think a vendor would sell a frag like that real willy-nilly. Most people really have to search them out, and they cost a lot compared to other frags. But, who knows, you my have one.
At any rate, go to the websites above, and it should tell you all you want about this coral.
