No. Move it to Low to medium light, Low to Low/Med Flow. Make him stretch a bit to get to the light... If he had completely detached they will still eat for 6 months to a year sometimes if the water conditions are better than good. Most will eventually parish. I currently am within my own elegance experiment. mine has bailed out completely around the edges. There are documents in a book somewhere of how elegance corals have grown a new skeleton after settling in the sand, but not visual proof that this has happened. The best advice I can give you is #1 don't skimp on the skimmer #2 if you cant do at the very least 15% water change weekly (not 30% every other week) give him to someone who will. They need a constant input of new water. I am doing 5% every 2 days. All automated except the salt... It has actually grown out since I got him but will still retract to the center of the skeleton when it gets dark sometimes. Good Luck and keep us posted.
