Sorry to jump in, but I just asked this same question on the reef forum. Are you talking about regular super glue that you buy in any old store???? And do you take the coral out of the water to do this???? I know that prob sounds like a silly question, but the process seems peculiar that you can remove them from the water, scrape them off and then superglue them onto another pc. of rock and put them back in the tank. Is that truly it, or am I missing some steps? Thanks for the input. Have several things I have been wanting to try and frag, but I'm so afraid of killing something! Corals cost sooo much!
