Green Spaghetti Finger Leather Help!!!

[landlocked303]

I have had this spaghetti leather for about two months now and it has been doing great until the last week. It has retracted all of its polyps and shrunk to 1/3 its normal size. I have checked the water parameters and everything is on par. All the other corals in the tank have had no changes. Any ideas?
