Sharp scissors. Take the frag and zip-tie it to a small chunk of LR. Tight enough so it won't slip out but not so tight that you rip the coral in half. Leave it in your buddys tank for a couple of weeks (until it attaches to the LR) then cut the zip-tie away and take it home.
+1 on the nip and zip,or rubber band,just not to tight as mentioned and in the same tank till its attached,just make sure its a nice clean cut with sharp scissors or razor blade and maybe place it in a bit of flow,not to strong to help keep the cut edge clean while it attaches to the piece of rock
A dull razor blade works just as good (just make sure it is clean of anything hazardous obviously lol), I have jabbed a toothpick through them and into a "pore" in the rock and held just fine even.... or a loose rubberband works too, or string even...................................
A dull razor blade ??? Why not a nice new fresh sharp blade ????
Ok I will let my buddy know that way it will save me a trip up there to do it and then another trip to pick it up . Does the cut need to be done in the water of is it ok to remove from tank perform the procedure affix to rock the put back in the tank ??
