Recommended underwater epoxy?

[Dez]

Hi,

I'm just wondering what you guys can recommend for underwater putty/epoxy that is reef safe for putting frag plugs in the display so that fish/snails/hermits don't knock them over. Also for putty-ing rocks together. I'm planning ahead in case I can't get it locally to give me lead time in ordering.

I have experience with AquaStik but that stuff doesn't stick very well.

I know crazy glue gel works but you can't really stick a tube in underwater to bond rocks together or glue a mounted frag on a plug down.

Thanks in advance for the advice.
