Why are they opening up?

I bought this a few days ago and the back half is opening up, but the front half isn’t. Why isn’t the rest of it opening up?

Could be something bothering them. Look for a little vermatid snail or worm near them. Could be just adjusting. Some take more time. These are individual animals and will do their own thing. Be patient and hopefully they will come out too. Nice zoas.

Looks like the back half may be shaded more than the front half.
