thanks for the tips guys, i'm already noticing that mine are getting closer and closer to the surface of the water....pretty soon, i may have a 6 pages post on "help, my xenia is growing too big for my tank" (HAHA FOR THOSE WHO KNOW =)
seriously, i think maybe going with the natural splitting idea will be better for me than to cut it up. i'm still kinda scared to do that, thinking i will end up killing it or something. that's why i haven't cut my colt coral yet. as fast as these i have are growing and spreading on their own, i really don't see a need to cut them. i'd like to get them growing on the glass, hell, i wouldn't mind having a xenia tank if it comes down to it =) grow away, i don't mind =)
hey ken, i think as long as you get the xenia secured to the rock long enough to have it attach on it's own, it doesn't really matter how you do it. i've been told i could also stick a toothpick through the base, and tie the toothpick to the rock, for easy removal later. you could also glue them. i'm convinced though that letting them do it on their own is the best way, just takes a few extra days....i got all the time i need, no rush.. =)
