not sure id buy corals of ebay to be honest with you
I agree, especially shipped two-day. It should be overnight or not at all.
Do a goggle search for "Tubastraea faulkneri". These are not easy, nor are they hard to keep. They just require attention. Like the auction stated, they do not use light as a food source so they need to be target fed a plankton and protien based food about three times a week. They are not a colony either, rather several individal animals living close together, so each polyp requires food in order to survive. I have some and they are wonderful. A great choice if you do not mind a little extra work.
