Smaller aquariums can be just as magnificent as larger sizes when they're beautifully designed. Sized at 20 gallons and under for compact displays, they'll fit perfectly on desks or on optional pedestals. Rounds and columnar shaped tanks include filtration and lighting systems that are easy to set up and maintain. They're a soothing addition to home or office and suited to housing fishes including tetras and guppies. Taking a minute to watch fish peacefully swimming in a desktop aquarium can be an instant stress reliever.
