i've heard that xenia is used in many tanks to help filter out phosphates. This is just my $0.02, but maybe the zenia needs a little bit of phosphates in the water coloumn to thrive. Following the same idea, it may be one of those corals that thrives in a "dirty" system, such as a nano tank, where the params and "dirt" are much more concentrated.
