1. Is it safe to use hot-glue in freshwater tanks? I have two pieces of Slate (i think its slate) that I want to hot-glue together to make a little cave. As far as I know, hot-glue and super-glue are safe to use as long as its completely dry.
2. What is this snail doing? First time iv seen anything like it.
Pics of both questions included.
