Fragging zoos..question

[McNasty]

I have some zoos dangling from the rock , 4 polyps to be exact and I was wondering how i could mount these to some small rubble rock safely. I have let them drop in the past hoping the would attach to a shellor something on the bottom, only to see them swept into some crevice in my rock work never to bhe seen again or float into my elegance coral and get gobbled up.

ANy suggestion would be welcome, has any one ever tried using gel crtazy glue? heard an elastic would work but wont the zoos just split apart and fall off the rock any ways?
