Help with plate coral

[All Seas]

Hey guys,

I picked up a purple plate coral a few months ago and it's been doing great. I go to check it out today and it looks different. None of the polyps are extended, the mouth looks a lot larger than normal and it looks as if it's turning green along the edges. I know its a bad Pic but take a look and let me know what you think.

Also, the only thing that changed is a decent piece of squid got caught in the polyps 2-3 days ago and he chomped it down.

Hard to tell anything from that picture.

It looks like it's getting ready to take a crap IMO. I paid it no mind in the past, but looking back my plate corals would look a little odd when this happened.

Just keep an eye on it. GL.
