The Asian glass catfish (Ailiidae) are a family of South Asian catfish . The species and genera of the Asian glass catfish used to be part of the Schilbeidae family together with the African glass catfish until molecular biological studies at the beginning of 2016 showed that they belong to a group of closely related Asian catfish families called "Big Asia", while most of the Schilbeidae belong to theirs African type genus Schilbe belong to the "Big Africa" ​​group. The Ailiidae occur in South Asia from the rivers of the Indian subcontinent across Southeast Asia (river basins of Chao Phraya , Mekong , Salween ) to Malaysia and Indonesia west of the Wallace Line .

features

They are 15 to 60 centimeters long fish with an elongated body that is laterally flattened at the rear, a short, far forward dorsal fin (missing in Ailia coila ) and a long anal fin . The close relationship of these three genera and their demarcation to the African glass catfish and the related catfish families of the "Big Asia" group is based on molecular biological studies and has so far hardly been supported by morphological characteristics. The belly line of the Asiatic glass catfish is generally curved, while that of the closely related Horabagridae is flat. The number of fin rays in the anal fin is between 39 and 55 in the Ailiidae. In the Horabagridae it is only 31 to 33.

Genera and species

Clupisoma garua

The Indian glass catfish , known from aquaristics , does not belong to the Asian glass catfish family, but to that of the real catfish (Siluridae).
