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?

Is any fish bothering it?? Is it shedding?? Is it to high in the tank try moving it around
