Attaching Frags?

[cam78]

If I get a small piece of zoas and want to attach them to a large piece of LR, UNDERWATER, is there some kind of glue that will bond underwater? I have nothing to attach them to and the current/fish knock them off. Suggestions, tips anything appreciated.

There are putty-like compounds that you can buy to attach frags to live rock. One brand is even sold on this site:

For smaller frags you can use super glue gel.
