Bro it doesn't matter whether the cloves are closed or opened. If water is good it will open.
But now you've shed some light tt your foxface has been sighted nibbling on it, chances are high it made a meal out of your cloves ><
Anyway all soft corals spread fast and well when conditions are right. Xenia and cloves alike, except from my experience it's not easy to handle Bali Xenia. Personally prefer Fiji Xenia more..
