I read a lot about superglue but it didn't work for me on soft coral frags. I think I will try the needle and thread method. I am about to get my first hard coral frags and was mainly looking for a way to attach them other than epoxy which didn't work on the soft corals either. Its kinda ugly looking in the tank for a long time. Maybe the superglue will work with the hard frags. Thanks for the help!
