My thoughts exactly, if my biggest problem is Xenia won't grow then so be it.Thanks everybody. It seems that for some it grows like weeds and others can't keep it alive. Mine was a frag that 4x in size in about 3 months, stayed the same about 3 months and now is all shriveled up. The part that amazes me is that all my other corals are doing better than ever, so I really don't want to mess with the tank too much.
