I wish you the best of luck. I had one (notice the word had). I had it for at least 6 months if not longer and then it just started to not have its polyps as open and streached like usual and then over a few weeks period the tisseue started dieing off and the entire thing bleached out. Had to go on a trip and when I came back all I had was its coral skeliton.
I know another person who had one for over 2 years and it was acutally growing like mad. Then like a switch was flipped it started to regress and over a period of months it died on him.
The 'experts' are not fully sure on its exact needs but many people have suggested that this coral will do best in less than optimal water quality. (ie it prefers dirty water to clean).
