Bagarius bagarius, also known as the devil catfish, dwarf goonch or goonch (Bengali: বাঘাইর), is a species of catfish in the genus Bagarius. It is generally reported as being found in large and medium rivers in South Asia,[3] and is likely synonymous with B. yarrelli.[1][4][5]

Taxonomy[]

Prior to 2021, the standard was to recognize two species of Bagarius from the Indian Subcontinent: First B. bagarius, supposedly a small species (up to 20 cm or 7.9 in) first described in 1822 by Francis Buchanan-Hamilton based on a specimen from the Ganges River.[1] The second is B. yarrelli, supposedly a very large species (up to 2 m or 6.6 ft) first described in 1839 by William Henry Sykes based on a specimen from the Mula-Mutha River.[4] Recent studies have not been able to document that more than one species exists in the Indian subcontinent, which, if confirmed, would mean that the name B. bagarius is a senior synonym of B. yarrelli, which was confirmed by a 2021 study.[1][4][6] In contrast, Southeast Asian populations from the Mekong and Chao Phraya basins typically included in B. bagarius likely represent a separate species, which a 2021 study found to be the new species .[1][7]

The larger type has been accused of several fatal attacks on humans in the Mahakali River that is Nepal's western border with India.

Aquarium[]

B. bagarius is the only member of the genus even marginally suitable for home aquaria. It requires cool, fast-flowing water, and eats bloodworms, shrimp and live or dead fish. Reports exist of very anti-social behaviour by these fish in captivity.
