hey, so I have an old 50 gallon tank that I used to hold a bearded dragon in like 8 or so years ago. It says somewhere on the tank that it's a critter holder, and not an aquarium(it's at my parents house and my mom was informing me about this). It's been water tested and it's held water for two days, but before I stick this in my second story apartment I want to make sure it wont spring a leak on me. Anyone have any idea on whether this is water worthy?
