easy steps for fragging softies
1) Get the largest tube of superglue, the GEL kinds are the best
2) Get large Tupperware bowl (temporary holding for pieces to be cut, cut pieces, and fresh mounts)
3) A bunch of paper towels (to dry and wipe slime off before superglue)
4) Dry live rock rubble or frag plugs
5) A pair of tweasers, this will allow you to mount polyps or soft pieces easily in the superglue without getting your figures stuck to it.
6) A pack of razors
the trick is to dab the coral on the paper towel to get the slime and water off it for a good superglue bound, use A LOT of superglue on a dry mount, and then place it in a the bowl to set, any pieces that come free you can try to remount.
One easy mount for xenia is simple sandwich it between two between two plugs with rubber bands while it is still attached to the colony, after week cut it at the base, if the xenia is stuck to both sides cut it down the middle with a sharp razor blade and you'll get two for one!
I like to let them sit in the bowl for a bit after mounting, if you introduce a lot of superglue to the display tank at once it can cause your skimmer to freak or some of the other corals to slime.
Cheers,
