Partial Zoa colony wont open

[JLH-l3ioCub3]

Have a fairly large Zoa colony that for the past week about 1/4 of it in one area won't open. I also have a Duncan that doesn't fully open or at Least is a bit deflated. All other corals are doing great. This just doesn't make sense. I haven't changed anything and all my params check out good. Even if something in the water was out of whack then it would affect more than just a select few Zoa polyps.. All help is appreciated... Im stumped!

Thanks so much for the time you took to share that with me! I read through it and started comparing the pics to my zoos and found that I had 2 tiny Asterina star fish on my zoa colony. I got them out and now the zoas are starting to open back up slowly but surely! Thanks again!
