I have a piece of live rock full of Xenia in my 45g reef tank. I wanted to cut some pieces off and put them on a frag plug or rubble rock or something. I have done some research and wanted to see what you guys think. There is about 20 heads on the rock, I didn't know if I should cut them while they are in my tank or take the whole rock out and cut the pieces in a tubberware? The rock is a base, holding up other pieces so it will be hard to get it out. Another question is once I cut it, should I put the pieces in Iodine or just tie them onto the plug/disc with a rubberband and mesh right away? Thanks in advance.
