Despite its unsuitability for the majority of home aquaria, this species is available in the aquarium trade on an irregular basis, and has also been marketed as ‘violet-gilled shark’, ‘red-gilled violet shark’ and ‘blushing violet shark’.

It appears likely that L. boga as currently recognised represents a complex of closely-related species.

This species can be identified by colour pattern comprising a brownish dorsal surface, yellowish flanks and abdomen, and a black to bluish lateral stripe extending from the eye to the caudal-fin base.

Found in various types of habitat but shows a marked preference for shallow, slow-moving and standing waters such as rice paddies and other temporally-inundated environments with dense aquatic vegetation.

This species is seen in the aquarium trade on a relatively frequent basis and is sometimes sold as ‘bicolor loach’ in the United States.

It can be distinguished from congeners by its unique colour pattern comprising 9-10 thin, yellowish bars on a dark background in the upper part of the body, and plain whitish colouration in the lower portion.

Like many fishes that naturally inhabit running waters it’s intolerant to the accumulation of organic wastes and requires spotless water at all times in order to thrive. It also does best if there is a high proportion of dissolved oxygen and moderate degree of water movement so external filters, powerheads, airstones, etc., should be employed as necessary.

This species has been widely regarded as a member of the genus Nemacheilus since the late 1970s with the vast majority of subsequent authors considering it as such, although in the aquarium hobby it’s more commonly referred to Schistura.

Probably a micropredator feeding on small insects, worms, crustaceans and other zooplankton in nature. In the aquarium it should accept dried foods of a suitable size but should not be fed these exclusively.

Daily meals of small live and frozen fare such as Daphnia, Artemia, Moina, etc., along with good quality flakes and granules will result in the best colouration and encourage the fish to come into breeding condition.

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…

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.

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…
