I am looking to upgrade my little 10 gallon tank for my two African Dwarf Frogs to a 20-50 gallon tank. If anyone has an old tank they aren't using, shoot me a message through these forums. I would, of course, ask that the tank doesn't leak and you would have the corresponding top/filter system for it. I wish I had the money and the secured floor to buy a 100 gallon tank, but I don't want to test 500 pounds of water upstairs!
