What causes zoas to "dome" like this?

These People Eater zoas have looked fine for weeks but a few days ago one of them started to over-open (turning itself into a dome shape), and then the other one started doing the same thing yesterday. None of my other zoas are exhibiting the same behavior.

Does anyone else have experience with this kind of behavior?

Not sure why the pictures didn't upload. Possibly too large? Let's size them down a bit and try again...

Further info... It seems like they are unable (or unwilling) to close up completely. I gave them a quick CoralRX dip and they shrunk while being handled and dipped, they didn't close. It's almost like they are "cramped" in the open position.

They should go back on their own.

My experience is they dome when the light level is too high for them. Other zoas look fine.

Hmmm what have you been dosing? They say call a doctor if it lasts longer than 4 hours.

Sorry can't help, but wanted to subscribe to this thread for info and replies as I'm curious.

What is the name of the zoas in the OP?

I have the same ones. They domed like that and stretched their mouths open wide while reef roids was in the tank yesterday.
