"Sure, it spreads, but maybe not to fast.." Yeah, that is what I thought. I had a two inch Xenia frag, bought back in october. By Christmas, it had takien over the entire top section of my reef. It is now in the process ( actually, they, its now 10 seperate colonies!!!) of trying to overgrow some orange zoas & light starve everything near it. Xenia is an aggressive colonizer. If that is OK with you keep it. One other thing, I've heard that its actually short-lived.
Anyway, its one of two things I wish I had not added NOW. The other being giant green Rhodactis 'shrooms, which are aggressively toxic to my other corals..
