Well, at the very end of the presentation, Dr. Ron mentioned that he lost his whole test group of gorgonians after his experiment concluded, due to gluing some frags with super glue and then he found out that it will kill the coral.

In MY experience (considerably less than Dr. Ron's experience!!!), I have seen gorgonians that were attached with glue and it did not seem to be an issue, but maybe there was something different going on with his conditions.

Scientific Coral Farms gives a very nice set of specific instructions on their website about how to frag gorgonians, by drilling a hole in the rock, stripping the flesh off the gorgonian down to the coral skeleton, inserting it into the rock and gluing it into the hole in the rock - and they propagate gorgonians all day long.

In light of Dr. Ron's findings, I might try that with putty if I ever got the courage to frag a gorg (I'm such a chicken about fragging!).
