Be Careful ...
I have accutally tried 3 different methods. The first one I placed a piece of my Star polyps under a rock and it took about 2 weeks for them to stay. The next one I rubberbanded and when the rubberband broke they stayed. But the best one i used is the super glue gel (MUST BE THE GEL ... my brother-in-law used the regular superglue

and when he placed the polyp in the tank it ran and his fish ate it.

It glued the fishes mouth shut

and he had to do surgery with a paperclip to get the fishes mouth open and pull the glue out GOOD NEWS!! the fish is fine!

) ... You can pick it up at any dollar tree store. Once you glue them on they are ussually out within the hour! GOOD LUCK!!
