There isn't much skeleton between the rock and the flesh, I never cut a coral before, I only asked about the saw blade because I would have more control with the blade than the dremel plus I wouldn't have to worry about heat. You make it sound tough, like one slip and it's a goner. Anyone in the area willing to come by and cut it off the rock for me. I really don't want to kill it. Alti I know you said they are pretty hardy but I have a brown thumb.
