Is there something wrong with this coral?

About four days ago this torch coral head began to lose/change colors. It was the same color as the other heads. No other corals in the tank have any possible issues like this. Picture below..

Have a similar torch, they from tonga and are collected a little deeper. If can lower it touch or stick in an overhang, for a few weeks and slower raise or pull out, will gain its color back. They can eventually handle more par, just need more time to adjust. If mounted to rock, just lower led output or raise the fixture a little. If have a par meter shoot for around 70 par to start.
