I guess I'm lucky, my toad fragged it'self. It willl start with a small piece getting a small "tear" in it, then it will progress to where the piece is hanging by just a little piece, so then I'll take it off and SG
it to a new rock, I've got 2 large (on is 12" across min, the other is 10" min) and 8 to 10 small ones (some as small as a small marble and some as large as 3 to 4" across).
I was told if you frag a toad you MUST take it out of the tank while you are cutting it. Take it out lay it on a towel and make your cuts, place them on your new rocks (I use SG
, but rubber bands work with low flow tanks) and place them back in the tank.
