Hello everyone,

I have a huge colony of pinwheels, and they've been in my tank for over 2 months. They have been doing great, and my clown fish have been sort of hosting them for a few weeks now. However, over the weekend, they shrivelled up all of a sudden. They are still all opened up, but it definitely doesn't look good. I don't think i've lost any polyps and I do have 1-2 heads that look normal. All my other zoas and corals look fine. I am very confused on what's happening. I checked all the params, and they are normal. Please help!

Here are the before and after pictures
