Raidāk

Badis blosyrus is a badid from western Assam and northern West Bengal in India, in the Brahmaputra drainage. Like most badids it is poorly documented. Its body patterning is almost identical to that of B. assamensis, but it is slightly smaller and has a noticeably elongated, better-developed jaw. In the Raidak River it was collected from cool, shallow, flowing water over small rocks and sand, with thick marginal vegetation.

Traded for years as 'Lal Cheng', Channa andrao is a snakehead endemic to the Brahmaputra River basin in northeastern India. It stays at a manageable size while showing much of the behaviour and colour of larger members of the genus. It lacks pelvic fins and is most often confused with C. bleheri, from which it differs in fin markings and in being a paternal mouthbrooder.
