Rather, the 60-gallon breeder is a standard 75-gallon aquarium, just not quite as tall. The 60-gallon breeder from Aqueon measures 48.5″ x 18.5″ x 18″. A 75-gallon measures 48.5″ x 18.5″ x 21.25″. As such, all the ancillary equipment, such as stands and glass canopies, are interchangeable between these models.
