45-gallon high aquarium with a lid. The tank has a slow leak that a fresh dose of caulk should cure. The middle top bracket is broken, but doesn't seem to bother anything. The back of the tank has hard water stains (hopefully the picture shows this). While this tank may not be used as a display tank, it would be excellent for growing out young angelfish, etc. Tank dimensions are: 36" long x 24" high x 12" wide.
