I'm in the process of creating my own nano aquarium decorations. I'm using a variety of safe substances such as crafting plastic mesh, rocks (tested and cleaned), glass, foam, and so on. I know that hot glue doesn't have the staying power in an aquarium setting. My question is what kind of glue/epoxy/whatever is best to use? I prefer if the end result is either white or transparent. I know that it's safe to use super glue/krazy glue that has cyanoacrylate as the active ingredient. I've used the gel version once already and it did pretty good. Any others?
