Frag coral first time

I have a frogspawn grow pretty big and now I want to frag them. I am thinking using a dremel tool for cutting but not sure what type of glue should I use. I google around they said you can use super clue but can I use super clue from home hardware store or home depot or they have to use specific clue that use for aquarium. Please advise on glue type to use and easy to get them.

Thanks,
