I have an elegance coral. Been in my tank about 7 months. It has been happy and heathy since I put it in. I keep it under 250watt halides in a moderate flow area. So far it shows no symptoms of the dreaded plague.
I couldn't advise anyone to purchase one though. A large number of the elegance corals I have seen at the lfs don't look so healthy, and eventually perish before being sold
.
I also keep goniopora and alveopora. I have had both for almost a year.
