Troubleshooting plate coral issues

[darkfisher]

Hey guys,

I recently got a purple plate coral and it's been thriving. Went to check on it today and it's looking off. No polyps extended, mouth's way bigger than normal, and it's got this greenish tint along the edges. Not the best pic, but take a look and give me your thoughts.

The only other thing that's happened recently is a big piece of squid got stuck in the polyps a few days ago, and it ate it.

Not much to go on with that pic, but I'll take a guess.

I think it's preparing to release some waste, if you ask me. I never paid much attention to this in the past, but now that I think about it, my plate corals would often look a bit off right before this happened. Just keep a close eye on it, and hopefully everything will turn out fine.
