Kumaradhara

The Canara pearlspot cichlid, Etroplus canarensis, appears to be endemic to the Kumaradhara-Netravati river system in southern Karnataka, India. Also known as the banded chromide or 'roman numeral' cichlid, it lives only in oxygen-rich fresh water, unlike its euryhaline relatives. Unmanaged collection raised concerns over its status, and commercial breeding in Southeast Asia has since reduced the pressure on wild stocks. Sexual maturity takes around 24 months.

Mesonoemacheilus petrubanarescui is a loach from the Netravati and Kabini river basins in the Western Ghats of southern India. It may be endemic to these two drainages. The dorsal surface carries 7-8 dark, saddle-shaped markings and the flanks a varying number of broken bars. It is unclear if it has been traded outside India, but it may turn up among shipments of M. guentheri or M. triangularis.

The Narayan barb, Pethia setnai, is a small cyprinid common in rivers draining the Western Ghats of India, described from Sanguem in Goa. It is widely traded as 'Puntius' narayani, though the trade fish all have the serrated dorsal-fin spine of P. setnai, a feature 'P.' narayani lacks. The central of its three dark flank markings, beneath the dorsal fin, is uniquely pale and diffuse. In hill streams and smaller rivers it gathers in backwater pools and deeper, slower areas.
