My devils hand leather has been doing really well up until this last week. It's been completely closed like it would be if it was agitated, but there's nothing I can see bothering it and I haven't added anything to my tank in the last 8 months. All my other corals look great, softies, LPS and SPS happy as can be.
What could cause only my devils hand leather to be unhappy?
