A friend of mine gave me a 120 gallon aquarium (I know... awesome friend). He had used the aquarium up until this point for a saltwater reef set-up. I think I want to make it into a vivarium. I was wondering if anyone has thought of any extremely useful applications for corner overflows in a vivarium? I would hate to cut the overflow boxes out and then learn I could have used them. Any suggestions or recommendations would be great!
