Considering that they are freshly fragged that wont help any that’s for sure.
Once they attach and get acclimated to your take and conditions they should be fine assuming all parameters are correct.
Xenia is a strange coral. It will pulse in my tank and not in yours it will grow like a weed in one tank and then one day have a mass die off with no apparent cause. No one is sure why they even pulse in the first place. I find that iodine and heavy light work great for me. My xenia frag tanks grow and pulse like crazy. To fast really. Some find it to be one of the easiest corals to keep alive and others can’t keep it alive at all. Like I said it’s an odd coral
