Zoas acting the fool??

[bwalders65]

Other zoas and corals in my tank are doing great.

Basically this coral just started acting weird the other day. It is a 3 polyp sunny D. For some reason it is closed up and one polyp is sticking halfway out. The other looks to have a ring pinched into it. Any ideas on what can be happening?

Is it a brand new frag to the tank? I have had the same thing happen to some new additions but after a period of several days they will open up fully. Try not to move them around so much since I have noticed it will keep them closed longer in this state. Just make sure they are in a nice area with flow.
