Does anybody know if Critter Cages by All Glass Aquarium (the tanks with built in sliding screens) will hold water? I have two African clawed frogs and I want to move them into their own tank, but the only spare tank I have is a 10 gallon Critter Cage. For whatever reason I always thought they weren't meant to hold water, but I'm not sure where that came from! Their website has turtles listed as an appropriate animal for this type of cage, but who knows what that means. I just don't want to have another leaking aquarium disaster
