Fragging LARGE Corals

[Marc Daniels]

I have a very large F. speciosa that I'm attempting to frag into several pieces. It is oval shaped, with one end at approx 1"+ thick, and tapers to over 3"+ on the other end. The "skeleton" is comprised of many things, the actual coral skeleton, rocks, mollusk shells, etc. I had a very hard time geting through the thin end with a dremel, and wanted some suggestions on what I could try using next. I have thought about chisel/hammer, but feaf it would be too destructive. I have also thought about a thin cable saw.

Any ideas, especially from anyone that has fragged a large, thick coral such as this?
