Hello, I have a fire belly newt in a 10 gallon tank. I keep the water fairly high. I am wanting to get another one, but I know I need more land. I would rather not buy a cave or something to that effect, because for one I would have to get a cave that is very high (probably would be expensive) and two some caves wouldn't be smooth enough. So, I was wondering how can I make my own land? Oh, and piling up rocks is not an option. thanks!
