Clowns don't host it. It spreads like crazy. In the 10 11 months I've had it, I've probably fragged 30 pcs by now. If you get some, situate it near the top - unless you want it to spread upwards very quickly and take over that section. Spreading sideways doesn't seem as overpowering as something reaching up to the light and covering everything in it its path.
I feed the standard DTs Phtoplankton and cyclopeeze weekly. Even before I started that, seemed as though my xenia feed of the the light. But AFAIK
, the micro-invert food is good for it and other coral you'll likely get.
