Aquarium fish

Kept in home and public aquariums. 403 fish on EveryFish so far.

Fishkeeping is one of the most popular pet hobbies in the world. Home aquariums hold freshwater fish such as guppies, tetras, barbs, gouramis, cichlids and catfish, and marine tanks keep clownfish, tangs and other reef fish. Public aquariums display sharks, rays and schools of ocean fish. Hundreds of millions of ornamental fish are traded each year, from more than a thousand species.

Where aquarium fish come from

Most freshwater aquarium fish sold today are bred on farms, many in South-East Asia, Florida and in India around Kolkata and Kolathur in Chennai. Goldfish, koi, guppies, mollies, bettas, angelfish and discus have been bred for colour and fin shape for generations. Most marine aquarium fish, by contrast, are still caught from reefs in Indonesia, the Philippines and elsewhere, though clownfish and some others are now bred in captivity.

India's wild ornamentals

India's rivers, especially in the Western Ghats and the North-East, hold many fish valued by aquarists. The Denison barb of Kerala became one of India's best-known aquarium exports, and heavy collection from the wild contributed to its decline before farm breeding took over much of the supply. Releasing aquarium fish into the wild has spread invasive species, such as the Amazon sailfin catfish now found in many Indian waters.
