Whats the longest time your zoa's have stayed closed after fragging them?

Reason: I fragged some Fri/ Sat and the none of them have opened back up since. Not even the mother colony. With these frags all I did was break a piece of the main rock off. No super glue or anything else was used.

Everything else in the tank is checking out good.

I'm sure they will be ok, they look fine....just closed.
