It looks like it might be a piece of the liverock it is on. Your xenia could be moving and as it moves along the rock it might give the illusion that it is something growing! Is it hard or soft?

They deffinately move i have on that moved from the rock he was on to a totally different live rock , took it a few weeks but he moved 6 inches , why it moved i have no idea
Looks like a piece of rock and the xenia is moving thus exposing it. I have a cespitularia that has moved a few inches already. Nothing to worry about.
