It would probably be safe to use epoxy. Most epoxy dries very hard, thus very unlikely to leach anything harmful in to your aquarium. But being the worrier that I am, I would take the time to buy a small tube of aquarium safe silicone. You can buy small tube at ACE Hardware for less than 3 dollars. This way, you know you are safe.
