P. chola was retained in Puntius sensu stricto, of which members are defined by the following combination of characters: adult size usually less than 120 mm SL; maxillary barbels absent or present; rostral barbels absent; 3-4 unbranched and 8 branched dorsal-fin rays; 3 unbranched and 5 branched anal-fin rays; last unbranched dorsal-fin ray weak or strong and unserrated; lateral line complete with 22-28 pored body scales…

Mostly known from slow-moving, relatively shallow tributaries and minor rivers with substrates of mud, sand or gravel. Aquatic plants are only occasionally present but riparian vegetation apparently grows thickly at some localities.

In the Schutunga River, part of the Mansai River drinage which is itself a tributary of the Brahmaputra in West Bengal state, In…

This species continues to be mislabelled as O. melastigma, a name currently considered invalid by the majority of recent workers, or O. javanicus, a valid but distinct taxon. Roberts (1998) demonstrated that MClelland’s description of Aplocheilus melastigmus, later renamed O. melastigma, does not correspond with any known Oryzias species from the Indian subcontinent or Myanmar since it’s said to have a dark spot in the dorsal-fin and an excessively slim body, among other anomalies.

This species was referred to as Dario sp. ‘Jaintia Hills’ or D. sp. ‘Bangladesh’ prior to its description.

Type locality is ‘India, Meghalaya, Jaintia Hills, Seinphoh stream at Umolong, 7 km from Jowai town, 25°31’36’’N 92°08’27’’E, 1320 m asl’, and in India it has not been found elsewhere to date.

This is one of the most frequently-traded members of the group and is an excellent choice for those new to keeping loaches. It’s distinguishable from congeners by a combination of characters including: rounded/truncate caudal-fin; a scaleless patch on top of the head; relatively large adult size; flanks with spotted patterning in females and a solid…

Sand-dwelling loaches from the families Botiidae, Cobitidae and Nemacheilidae are also suitable but proper research is essential as some can be excessively territorial or otherwise aggressive.

A community based around fishes from its natural waters could include species such as Badis badis,…

This is one of the most frequently-traded members of the genus and is an excellent choice for those new to keeping loaches.

It’s distinguishable from congeners by a combination of characters including: relatively large adult size (to at least 80 mm SL); rounded/truncate caud…

This species is almost unheard of in the hobby with the specimen pictured above the only one we're aware of. It was imported into the United Kingdom in late 2011 as bycatch among a shipment of mastacembelid eels from northern India, and the identification was subsequently confirmed by Justin Havird, senior author of the most recent revision of the genus.

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.
