Sexual differences: The males tend to be more slender than the females and are described as having serrations on the posterior edge of the pectoral fin spines, whilst the female’s pectoral fins lack these serrations.
Breeding: There are no known documented spawnings of this catfish in aquaria, which is most likely due to the fact that this catfish is rarely imported and also due to the size of aquarium required. Whilst there are no documented aquarium spawnings it is documented that these catfish are bred in India using hormone injections.
Diet: The natural diet of this catfish includes vegetable matter, fish, crustaceans and molluscs. In captivity these catfish readily accept catfish pellets, prawns and frozen foods.
Compatibility: Ompok bimaculatus is described as being peaceful but, has quite a large mouth, and it is for this reason that I would suggest that you keep this catfish as part of a shoal of its own kind or with other large species of fish.
Colouration: The base colour of the body is brown, which is usually marmorated or blotchy with a conspicuous round black blotch above and behind the pectoral fin base. The second of the two spots is at the base of the caudal peduncle hence the name Ompok bimaculatus!

The pelvic fins are described as being small with 7-8 soft rays. The pectoral fins have 12-14 soft rays. The caudal fin is forked. Ompok bimaculatus has two pairs of barbels; one pair of maxillary barbels which reach the reaching anal fin; and one pair of mandibular barbels which are described as being small in length. The eyes are small and are covered by skin. Ompok bimaculatus is described as having vomerine teeth in 2 patches.
