Attaching corals to rock?

[toytech]

Get some underwater epoxy , the kind that comes as a stick and you knead it together . I either drill a hole in the rock or find a crevice to stick the end of the plug in and then make a ring of epoxy to stick to the underside of the plug . Push the plug into the hole until the epoxy sticks to the rock and your done . Before i started doing this all my frags ended up in the sand and it was driving me nuts.
