Xenia can be a pain in my experience. LOL Sometimes mine are pulsing like crazy sometimes they just sit there. i think it has to do with your water chemistry. I have mine in a relatively hi flow area right now and they are still pulsing. And spreading like crazy. i would keep it isolated so that it doesn't spread to every part of your tank. I've seen tanks where its growing off the walls lol
