All zoas in umbrellas at the same time

[Just John]

I am not too concerned, but really curious. I have at least 20 different zoa colonies and frags and even though nothing (parameter's, temp, etc.) has changed at all in the tank, every one of them went into that umbrella shape at virtually the exact same time and have been like that for a day. I have had one colony do this now and then, but never all on them at once. Has anyone else had this happen?

Pictures? Also there's lots of things we can't test for including various biological toxins that can be produced by things we can't even see...

I'm not home right now, so I can't take any pics, but it's that standard umbrella look. I don't have any fish in this tank, just corals, so there is not anything to produce a toxic, lol, poop. Hopefully they will be back to normal when I get home. Otherwise, I think they should recover before long so I'm not too concerned right now.
