Fish Tanks & Aquarium Fish Tanks

An aquarium or fish tank is typically a large glass enclosure consisting of at least one transparent side in which water-dwelling plants or animals are kept. Fishkeepers use aquariums to keep fish, invertebrates, amphibians, marine mammals, and aquatic plants. The term combines the Latin root aqua, meaning water, with the suffix -arium, meaning “a place for relating to”.


Fish tanks come in many sizes and shapes. Most commonly, you will find 25 Gallon Fish Tanks, 55 Gallon Fish Tanks, 75 Gallon Fish Tanks, 100 Gallon Fish Tanks, and 125 Gallon Fish Tanks. An aquarium can range from a small glass bowl containing less than a litre (34 fl.oz.) of water to immense public aquaria which can house entire ecosystems such as kelp forests. Larger aquaria are typically recommended to hobbyists due to their resistance to rapid fluctuations of temperature and pH, allowing for greater system stability.

Reef aquaria under 100 litres (20 gal) have a special place in the aquarium hobby; these aquaria, termed nano reefs (when used in reefkeeping), have a small water volume.

Practical limitations of Aquarium Fish Tanks, most notably the weight (one litre of fresh water has a mass of 1 kilogram (8.3 lb gal-1), and salt water is even denser) and internal water pressure (requiring thick, strong glass siding) of a large aquarium, keep most home aquaria to a maximum of around 1 cubic metre in volume (1,000 kg or 2,200 lb). Some aquarists, however, have constructed aquaria of up to many thousands of litres.

Aquarium Fish Tanks within public Fish Tanks designed for exhibition of large species or environments can be dramatically larger than any home aquarium. The Shedd Aquarium in Chicago, for example, features an individual aquarium of 7.7 million litres (2 million gallons). Sometimes you will find saltwater fish tanks being held up by a Fish Tank Stand. Essential components of a fish tank include fish tank filters.
