The popularity of mini-aquariums (defined as water features that contain less than 40 gallons of water) is on the rise. If you live in a small apartment, want to set up a mini-pond at the office, or just prefer the look of a tiny tank, a mini aquarium may be the perfect choice for you! These systems can be freshwater or saltwater, can be filled with a wide variety of species, and generally take up a very small amount of space. Mini-Aquariums offers detailed information on all aspects of setting up and maintaining a mini aquarium. It includes sections on fish health and water quality management, explains the differences between aqua-terrariums, terrariums and vivariums, details how to use common species of terrestrial plants in container ponds, and provides extensive information on many other topics.
