Sorry to tell you this but those corals are extremely hard to keep. I have not met anyone that has keep one alive longer than 6 months. I think they are one of the prettiest corals you can get, but they are a pain. They have to have perfect water quality. I had a green one (when I bought it I didnt know they were hard to keep) but my clown fish played in it and it eventually died. My LFS stuck me pretty good with that coral. Mine closed up for a while and started to decay away. I tossed it out and just ate that 45 dollars.
