How to frag safely?

[TacticalTanking]

So I watched the video in the "Sticky Threads" area, but I have a bit of a problem. My Reverse Space Monsters colony (which is huge) has grown on to 3 different rocks, and I want to frag it since I have a smaller colony which was next to it when I got them, but now the Space Monsters have literally grown all around it and everywhere else and is starting to cover the other (much much smaller) colony up. Should I frag them in the tank or out? I have only a few rocks (20gal cube tank) so I'd have to take everything out.

Let's see if we can get some help...
