Fastening small Frags

[JohnnyReeftank]

Hey Guys,

I'm pretty new to the game and I was wondering what you guys use to fasten your small frags to your live rock. I've been trying that runny Coralaffix glue but it doesn't seem to work. So far I have just been kind of cramming everything together and wedging frags into place, but they are still unstable when I want to rearrange my rockwork. I used underwater epoxy to fasten my live rock together and it was hit and miss. Any suggestions or should I just keep cramming?
