pulsating xenia

Can be very prolific, out compete other corals for space.

I keep my iodine levels high. The Xenia is also near the top of my tank with lots of water flow. It seems to do well in these conditions, but I am using a 130 watt pc (planning on upgrading to MH next month). A friend of mine uses MH, he keeps his Xenia near the top of the tank, it does really well with a base that is 1 1/2 inch to 2 inches round. His splits a couple of times a month. He also keeps elevated iodine levels and adds Phytofeast and DT's twice a week. We have found that by watching the Xenia you can tell when your iodine levels are low.
