Also, I hope you know that they are aposymbiotic corals. They do not get any benefit from lighting. They rely entirely on feeding. Often it is necessary to start off either by feeding them at night (when their polyps are in feeding mode, typically) or by training them to open in the day. That can usually be accomplished by thawing out some brine shrimp in a glass of tank water and using a turkey baster to blow some of the "juice" onto the coral to provoke a feeding response.
Not an extremely difficult coral to keep once you have the feeding thing down, but that is more of a hassle than some people care to deal with. Good luck!
