Have you checked your water parameters? If so please list them here. I see some other in the background are closed up as well so I am thinking something is off.

Your tank doesn't look very mature, everything is white. I'm guessing, your nitrates are zero or close to it, phosohate is probably low as well. Alzo, i see hair aldae or bryopsis on the rasta frag , that could irritate it.

Do you have fish dumping sand on it?
If it's not sand, try dipping it to make sure you don't have pest.

Is it isolated to just these rastas? Looks like your other zoas are not opening up fully either.

It could be all above.

My best guess is more light , all your zoas are extended. If they dont get enough light they will realease them selfs and float somewhere in the hopes of beter lighting.
