Zoas in the air

I've got lr high up in my tank, one is covered in zoas they seem to be underdeveloped at mo bc they've not opened up yet, my question is this, is it ok to expose them to the air when I do a water change, waiting fort new aqua one light system to arrive, that is why they are at the top nearer the light

I know SPS corals are exposed to air for some moderate periods of time in shallow waters, but don't know about zoas. I know a couple seconds of exposing them to air by transferring them wouldn't hurt, but I don't know about 5,10,15 or more minutes. Might just want to be safe and move them down, then move them back.

I've exposed my picky high light zoas to light for 10 min while doing a WC and they were just fine

Thanks guys, it's only a nano 12g I think I'll do it quickly and leave them in place, its getting kind of full in there,
Ps any idea what I should do with a nudibranch, it's on my glass and easy picking.
Think I'll introduce him to the sewers of great Britain

I might be wrong on this, but I think that they're exposed to air at low tide. They close up and produce a mucus covering when exposed to air to keep themselves safe. So exposure to air shouldn't hurt them.

I've seen pictures of some zoas in Hawaii that are only covered by water during high tide, completely exposed during low tide. I'd say that the few minutes they're exposed during a water change should be no harm.
