Is a paly bending like this healthy?

I just put this utter chaos frag with some other corals in yesterday. It opened up immedietly and seemed to be doing good but is this from stress or normal. Ive never seen one open like this and it opened normally yesterday.

As in the top and left side are opened further than the rest making it looked a bit contorted.
