Godavari

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 is available sporadically and makes an excellent choice for those new to keeping loaches. It's distinguishable from congeners by a combination of characters including: truncate/rounded caudal-fin; no scales on top of head; dark, squarish spots o...

This species is still considered a member of the genus Nemacheilus by some sources, but it was reclassified and placed in Acanthocobitis by Grant (2008). Acanthocobitis sinuata, generally considered a junior synonym of A. mooreh (Kottelat, 2012b), also appears distinct and differs in geographical distribution plus number of dorsal-fin rays (2-3/9-10 in A. mooreh vs. 2/8-9 in A. sinuata) and some aspects of colour pattern.

This species is clearly unsuitable for the home aquarium given its eventual size and natural behaviour, and we know of only a handful of private aquarists with the facilities required to house it long-term. The grouping currently contains four species but is in urgent need of review with a number of additional taxa thought to exist and B. yarrelli possibly representing a synonym of B. bagarius.

This species is endemic to and widespread within peninsular India, where it has been recorded from the states of Gujrat, Madhya Pradesh, Chhattisgarh, Orissa, Jharkhand, West Bengal, Maharashtra, Andhra Pradesh, Goa, Karnataka, Tamil Nadu and Kerala. It is thus found in numerous river systems of which some of the most important include the Tapti, Narmada, Mahanadi, Godavari, Krishna, and Cauvery.
