Up for auction is a non-leaking 37 gallon aquarium. It measures 30 1/2"W x 12 1/2"D x 22 3/4"H. (a really tall 20 long) I used it as a sump for many years and didn't leak when I took it out of service. It's dirty, but should clean up good. It would make a nice tank for breeding tall fish, such as angelfish or discus.
