Unhappy zoa polyp

[Mike N]

I have a frag tank with some zoas in it, and they have been doing well up to this point.
One of the polyps on this frag plug looks unhappy, the skirt is folded backwards. The other large polyp on the plug is doing just fine, as well as many varieties of other zoas that also look happy.
Any idea what's going on?

I've been watching the team very closely and haven't seen any potential Predators other than some amphipods.

They look perfectly fine to me. How long have you had them. Skirts on zoas and vary depending on flow, light, water quality.

Like I stated these look just fine. Don't mess with them let them keep on going.

Now if they close up really tight looking like a small marble or bb then you would have an issue.

Zoas are some of the most difficult corals in my opinion. They also seem to be the easiest at the same time. They'll grow like crazy and out of no where, melt for absolutely no reason known. Anyone else feels like that?

I'm right there with you on that bud
