anyone have any experience in this matter? care to share?

I've seen a Australian scoly fragged before. A nice bandsaw with a diamond-tipped blade made short but neat work of it. I think bisecting the mouth is a necessity for success.

get a dremel if you don't have a bandsaw and cut cleanly

I think if you were to get a rubberband and put it over the mouth, it would kill some of the tissue so you could frag it easier. I bet a dremel would work, I think I've seen it before.

use a dremmel or bandsaw... those are your best bets.. i have done it before and it was all well for me
