Yes "super glue" gel is the thing to use. A gentle dip in tank water will set up the gel...then place in your tank....I still loss a few LoL.
Also when cutting/scapping off the LR, try to get a thin layer of coraline/LR left on the polyp bottom\, as a tag to glue ....FYI try not to crush,cut, mutilate ,staple or cover the polyps with glue.
ALSO***Very Important!!!!** wear gloves and some sort of eye protection as zoos can carry a NASTY (as in DEADLY) toxin.
(I got just a micro squirt on an eye lid and had a sore red eye for days)
Good Luck
PS what colors do you have
?
