[1][2] This species reaches a maximum length of 20 to 22 cm (7.9 to 8.7 in)[2] Bagarius vegrandis 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.
