Thanks scottay! The xenia is already growing, even after a few weeks. There are already a few new heads popping up.
Which zoa head? The original original one that hitch hiked on the live rock? It is still alive, but doesn't ever open. I am sure I nuked it really well since I ran the lights at 90%+ during cycling for several days in a row. But, it still has color, and I can see it hiding down in the rock... it just never extends.
