Great tank Damon!
Your Xenia is going ballistic, that is probably what my tank is going to look like in about 6 months. I keep telling my wife to let me trade in the mother colony of my Xenia and get something else, but she won't let me. Now I have two other Xenia colonies across my tank, one is growing very fast right behind my toadstools. That one has taken off because it is right smack in the middle of my tank, up high, absorbing the MH light with no sun tan lotion on!
At least down here in South FLA, most LFS will only take a couple of Xenia frags a month, otherwise, you are gardening.
