I guess I still have some bright spots. I have a xenia frag that grows like a weed. When I was moving LR around I knocked it off the super glue. I set it out in the sandbed with no rocks around for it to spread too. I filled in the frag as much as it could and it aparentily was not going to be stopped from spreading further. It was checking the tank one night with a flashlight and notice 2 chuncks of xenia loosily bouncing around the sandbed.
Thinking something was eating my xenia I kept a eye on them. I next mourning one was gone and the other was attacted to some live rock like 8" away. I had no idea xenia could do this but good luck to anybody trying to stop xenia from spreading.
