Kryptopterus geminus is a species of catfish belonging to the family Siluridae. It can be distinguished from all its congeners, with the exception of Kryptopterus cryptopterus , by the almost flat dorsal profile with no concavity behind the head. This species grows to a length of 17.1 centimetres (6.7 in) SL. [2]
Examples of this distinctively shaped, translucent fish used to be assigned to the long-established species K. cryptopterus but recent studies have shown several small but consistent differences which prompted the erection of this new species. It has been recorded in Cambodia, Laos, Thailand and Vietnam. K. geminus can be distinguished from this close relative by its narrower head, longer snout, longer anal fin and eyes located much more laterally. [3]
Kryptopterus bicirrhis, often called the glass catfish, is an Asian glass catfish species of the genus Kryptopterus. Until 1989, the concept of K. bicirrhis included its smaller relative Kryptopterus vitreolus. Its scientific name K. bicirrhis and common name glass catfish are often still used in the aquarium fish trade to refer to the actual K. vitreolus; as it seems, the larger and more aggressive true K. bicirrhis was only ever exported in insignificant numbers.
Clarias is a genus of catfishes of the family Clariidae, the airbreathing catfishes. The name is derived from the Greek chlaros, which means lively, in reference to the ability of the fish to live for a long time out of water.

These species are distributed in the Black Sea basin, northern Turkey, south and east to the Yangtze River drainage in China and south throughout Indo-China to Java, Indonesia. They are found in Asia Minor and southwards to Southeast Asia. The genus is very diverse in the Indian subcontinent. Southeast Asian species tend to have restricted distributions.
Kryptopterus is a genus of catfishes belonging to the family Siluridae. They are found in freshwater throughout Southeast Asia. The scientific name comes from Ancient Greek kryptós + ptéryx. It refers to the reduced or even entirely absent dorsal fin of these catfishes.
Kryptopterus cryptopterus is a species of catfish, the type species of the genus Kryptopterus. It can be distinguished from all its congeners, with the exception of the newly split Kryptopterus geminus, by the almost flat dorsal profile with no concavity behind the head. This species grows to a length of 14.6 centimetres (5.7 in) SL.

E. labiatum is known from the Brahmaputra drainage in north-eastern India, but has also been recorded in the Salween drainage in Burma, the Ayeyarwady drainage in China, and the Brahmaputra drainage in Tibet and Burma. E. stuarti is from the Ayeyarwady River of Burma and India; however, it has not been collected since its original discovery. E. labiatum is found in mountain rapids.

There are also unconfirmed reports from Penang, Malaysia.
