 Contents
An aquarium is a clear-sided container (typically constructed of glass or high-strength plastic) in which water-dwelling plants and animals (usually fish) are kept in captivity.) The term is also used of a public establishment that maintains a number of aquatic species in captivity, much as a zoo does for land animals.

1 Aquarium history and development

1.1 Ancient practices

The keeping of fish in confined or artificial environments is a practice with deep roots in history. Ancient Sumerians were known to keep wild-caught fish in ponds, before preparing them for meals. In China, selective breeding of carp into today’s popular koi and goldfish is believed to have begun over 2,000 years ago. Many other cultures also have a history of keeping fish for both functional and decorative purposes.

1.2 Glass enclosures

The concept of an aquarium, designed for the observation of fish in an enclosed, transparent tank to be kept indoors, emerged more recently. However, it is difficult to pinpoint the exact date of this development. In 1665 the diarist Samuel Pepys recorded seeing in London "a fine rarity, of fishes kept in a glass of water, that will live so forever, and finely marked they are, being foreign". The fish observed by Pepys were likely to have been the paradisefish, Macropodus opercularis , a familiar garden fish in Canton, China, where the East India CompanyThe British East India Company popularly known as John Company was founded by a Royal Charter of Queen Elizabeth I on December 31, 1600.
