Do you notice any fish or invert picking at them?

Look for something like vermetid snails in the middle of them. It looks like something might be aggravating them a bit. When I saw mine doing this, it was indeed vermetids.

First look very closely with a flashlight when they are closed at night. If it is vermetid snails, you will see them then. They have a very hard crusted tube that they come out of. If that is what they are, can you remove the rock they are on? I removed mine by pulling the frag they were on and putting in a shallow container of tank water, then take some tweezers and remove the vermetid. you have to get it at the very base as that is where the actual snail it. If you do not see anything with a flashlight when they are closed up, I am not sure what the next step would be.
