Horabagrus is a small genus of bagrid catfishes endemic to Kerala, India. H. brachysoma is an important food fish and members of this genus can be found in the aquarium trade.[1]

Taxonomy

The genus Horabagrus is usually classified under the family Bagridae, but there are disagreements. The genus name is after the Indian zoologist Sunder Lal Hora. Though listed under Bagridae, Horabagrus is not listed under either of the two Bagrid subfamilies by the All Catfish Species Inventory.[2] In Nelson (2006), the genus is provisionally placed in the family Schilbeidae, where it is sometimes recognized as its own subfamily. In de Pinna (1998), this genus is classified as sister to the catfishes Pangasiidae and above, which would require a separate family.[3] This genus has also been classified in its own family "Horabagridae".[4] In a 2007 paper, Horabagrus was not classified under any current catfish families.[5]

Species

There are currently three recognized species in this genus:[1][6]

In the Aquarium

H. brachysoma is a common fish in the aquarium trade. H. nigricollaris is more seldom seen because it is not commercially farmed like the former.[7] Nevertheless, the care for these two species is similar. These fish are adaptable and are not picky about water conditions; also, they are hardy and easy to feed. However, these fish are light-shy and require plants or decorations to hide underneath for darkness; these fish are relatively secretive during the day.[7][8]
