Guys, I have some zoas that I got from a fellow reefer. They are attached to some eggcrate. I tried unsuccessfuly to move some of them to a piece of live rock. They were attached (or so I thought), but after having been in the tank a while they blew of the rock. What did I do wrong? I used locktite superglue(cyanoacrylate). Patted the rock and the zoas dry with papertowel, but they came off. Is there a special technique that I'm missing? Any help wouidl be greatly appreciated.
