Within the nominal species grouping suggested by Grant (2007) almost all B. rostrata sold in the hobby are B. sp. 'upper Brahmaputra' with B. rostrata sensu stricto rarely, if ever, available. Trade names include 'Gangetic loach', 'twin-banded loach' and 'ladder loach'. The defining characters of the group are "Pattern consisiting of 8-10 black to dark brown body bars that exhibit pale and numerous spots in juveniles, and in adults the bars can anast…

To date known only from the Jaintia Hills district, Meghalaya state, northeastern India meaning its natural waters are part of the Brahmaputra River system. The type locality is given as ‘Tre Rangriang, Jowai’ in the description paper, but we’ve been unable to locate this on any map. The paratypes were collected at ‘Thlu Muwi’, which probably refers to the ancient stone bridge built over the Muwi stream, a place popular with tourists due to the nearby Muwi waterfalls.

According to Kottelat (1990) the chief distinguishing characters for the genus are: possession of 9-18½ branched dorsal-fin rays; colour pattern without black basal caudal bar, but with an ocellus at upper base of caudal-fin; upper lip with or without several rows of papillae; lower lip with a broad median interruption and a widened, papillated pad on each side.

This species may be seen listed as a member of Nemacheilus or the nomen nudum Noemacheilus in older literature and is sometimes sold as 'red tailed, striped sand loach' or 'red tailed squirrel loach'.

This species isn’t common in the trade but occasional specimens may be found among shipments of wild caught fishes from northeast India, and it’s sometimes seen on sale as ‘pan…

Endemic to the Ganges and Brahmaputra river basins and thus occurs in northern India, Nepal and Bangladesh. Type locality is ‘the Yamuna River, and northern rivers of Behar and Bengal’.

The distribution of the genus as a whole is interesting because these fish occupy the area that geographically separates Indian and Southeast Asia barbs and it has been theorised that they may represent an evolutionary ‘link’ species…

C. latius isn't often available in the trade but makes an excellent alternative to more commonly-offered members of the genus should you be lucky enough to find some. Shipments of similar-looking Indian Garra species such as G. mullya or G. gotyla sometimes contain the odd specimen. It exhibits morphological differences when compared with other members of the genus and may be assigned to a separate taxon at some point in the future.

Like most badids this species is poorly documented and has yet to find significant popularity in the aquarium hobby. It is easily confused with B. assamensis at first glance as the body patterning of the two is almost identical but can be distinguished by its slightly smaller adult size, noticeably elongated, more well-developed jaw profile and some other, mostly internal, meristic characters.

An assortment of undescribed Oreichthys spp. from India, Myanmar and Thailand are currently traded as O. cosuatis. It can be distinguished from other described members of the genus by lacking a black blotch on the caudal peduncle, plus the following combination of characters: 2-3 perforated scales in lateral line; ½6½ between pelvic-fin origin and dorsal midline; presence of dark stripe in centre of anal-fin, forming a triangular blotch in adult individuals; dorsal-fin with whitish tip and broad, black, subdistal margin in the upper portion of the fin; 11-13 rows…
