Shrooms and zoas closing down

[7hogwarts]

This may seem odd but my Shrooms and zoas are closing up tight. My sps and lps look fine.

Everything looked fine 2 days ago. last night stuff just looked off. I have a clam that looked kinda poor too. It looks fine now. I worry because I have some very high end shrooms.

I did add a Fromia starfish that isn't looking good. But might make it. Do they release any toxins?

I did a 10% water change this morning. Things aren't looking any better.

Do another water change in the morning?

I always think to start running carbon when something like that starts. Have you tested your other levels? Did the starfish die?

I did change out carbon. The starfish did not die and has crawled around a bit.
