$12 here for a 10 gallon. If you need it for a QT you would be better off with a larger tank, tens are ok, depending what you need it for, right now I have two small clowns in a ten, and they are small, but they are still need more room, and they are only maybe 1 1/2 inches long. They use every inch of the ten gallon. Waiting for my stand so they can go in the 40 gallon breeder.
