Aquarium

An aquarium (plural aquariums or aquaria) is a vivarium consisting of at least one transparent side in which water-dwelling plants or animals are kept. Aquaria are primarily used for fishkeeping, although invertebrates, amphibians, marine mammals, and aquatic plants are also housed in aquaria. The term combines the Latin root aqua, meaning water, with the suffix -arium, meaning "a place for relating to".

The aquarium has a long history and maintaining an aquarium has become immensely popular worldwide; a person who owns or maintains an aquarium is known as an aquarist. Aquaria can come in a variety of materials, shapes, and sizes. They are typically constructed of glass or high-strength plastic. Cuboid aquaria are also known as fish tanks or simply tanks, while bowl-shaped aquaria are also known as fish bowls. Size can range from a small glass bowl to immense public aquaria. A number of components are used to maintain appropriate water quality and characteristics suitable for the aquarium's residents. There are many types of aquaria, classified by the organisms maintained or the type of environment that is mimicked.
