zoanthids Some open, Some closed

So I have a punk rocker zoanthid that looks great. The frag has about 5 heads on it. Well during the day only one or two will open fully, the others stay closed. I have tried to move it in the tank with the same results. All my other zoanthids are doing great in the tank.

So my question is something attached to it freaking it out? I blow it off daily with a baster but it doesn't help. Only coral in my system that isn't happy, but yet some of it heads do open.

Any ideas?
