That might be the cause. They should relax within a few hours to a couple of days. They are sensitive to changes just like any other coral. I would t worry.
Like I said, they are sensitive. The fruit loops look good and opened. Do you have a powerhead blowing on them? Did you feed the tank right before you took the pics? What are your levels? What kind of lighting is it and how high are they turned up?
Also look for nudis crawling on them or some type of pests . Sometimes some of mine do this and not others but after a few days they pop open . They have a mind of their own lol .
