What is this zoa doing?

I have these Psychfriggindelic zoas that are exhibiting the following behavior (see pic). What is the cause of that convex shape? The enlarged mouth is something new. They do revert back to being flat like the one on the left.

Btw, the concavity is most extreme during feeding times and when pumps are off. But the concavity is what concerns me. I always thought my lighting would be somewhat inadequate so I placed it in a high light zone.
