Cloudy and not in a good way

[sitandwatch]

So I get home and I look at the tank and its really cloudy so I am thinking I should clean the glass.... And nope that did not help I have no idea what happened but I have a few interesting things.

1) My Zoa looks eaten maybe not sure but its gone
2) The mushrooms are shriveled up
3) Hammer Coral is tight not loose and wavy
4) some sps frags are not happy
5) One dead snail
6) really cloudy water

All the fish seem fine they ate like champs the fish are (2 true percs, Pajama Cardinal, Mystery Wrasse, Blue spot jaw fish)

Peppermint shrimp still around and seems fine.

Ammonia, nitrates, nitrites all zero

I also believe that I have a eunice worm hiding in the rock.

any ideas what happened?
