Super Glue gel is often used by reef keepers to glue coral frags to rock. It works and works well...and is perfectly safe to use underwater as previously mentioned. The pro to using it is that it sets immediately and there is no cure time involved.
Wooooohhh! Great Cave! I'm from Colorado, and unfortunately, I may soon have to evacuate my home. I'm bringing my favorite fish with me, my cats, dog, chinchilla, etc. I actually just got into silicon for a different project I'm working on. Depending on how long I can stay, I will probably build a cave with it! Or the super glue gel, either would work.
