It registerd a growth of 66.55 % in terms of quantity and 20.59% in terms of value in INR. India has great potentials in Ornamental fish production due to the presence of rich biodiversity of species, favourable climatic conditions and availability of cheap labour. Kerala, Tamil Nadu and West Bengal mainly practice ornamental fish farming in India. The ornamental species are categorized into indigenous and exotic. Availability of a vast number of native species has contributed significantly to the development of ornamental fish industry in the country. North-eastern states, West Bengal, Kerala and Tamil Nadu are blessed with potential indigenous species. About 90% of native species (85% are from northeast India) are collected and reared to meet export demand. Presently, nearly about 100 native species are reared as aquarium fish. There is also a great demand for exotic species due to its colour, shape and appearance. More than 300 exotic species are covered in the ornamental fish trade, but a greater demand for this exists. About 200 species are bred in India. 90% of India exports go from Kolkata followed by 8% from Mumbai and 2% from Chennai.

They come under eight closely related families namely, Anabantidae, Callichthyidae, Characidae, Cichlidae, Cobitidae, Cyprinodontidae, Cyprinidae and Poeciliidae. Aquarium fishes are mainly categorized into two groups namely, egg layers (oviparous) and live bearers (ovo-viviparous). Majority of aquarium species are egg layers and normally external fertilization occurs. Based on this, it is again categorized into the following types. egg scatter laying non-adhesive eggs egg scatter laying adhesive eggs egg buriers mouth incubators nest-builders and egg-carriers Commercially important indigenous species The commercially important indigenous and non-indigenous species list are presented below.
