While I would certainly be interested in trying some Xenia, all I have to trade right now is fragments of stuff Michael gave me (bullseye buttons and maybe a tiny frag of finger leather), so you probably already have them from Michael.

If nobody gives you a better offer for that potential second chunk of Xenia, let me know. From what I've read about Xenia, I'm sure you'll have more to trade in a few weeks.

It's Xenia (many polyps on one thicker stalk) not Anthelia (one polyp per stalk), right?
I've read one interesting side effect of Xenia is that they functionally act as living skimmers, reducing nutrients directly from the water. Have you seen a reduction in skimmed ooze after you added them? Just curious.
