Mesonoemacheilus sp.


Heiko Bleher reports on a new species of Mesonoemacheilus loach he discovered during a recent expedition to India.

Origin: Chalakkudy river, India.

Water: pH 7.67, GH 3, water 26.6°C/80°F, air 37.3°C/99°F.

Habitat: Clear, strongly-flowing water running over rocky ground of giant stone slabs and large round black rocks. There were no aquatic plants.

Notes: The balitorid loach genus Mesonoemacheilus includes five species from the Indian Peninsula, four of which are from Kerala. I found more than five different ones between Mumbai and Travancore.

The five new species I discovered and the five already described rarely exceed 6cm/2.4”, with most of them, like the species featured here, reaching just 4.5cm/1.8”. Some of the new species are now being exported.

These fish live in fast-flowing water with quieter peripheral zones. They need small and large rounded rocks, driftwood, large-grained sand and a medium to fast flow. They’ll accept general foods and are easy to keep, even in slightly smaller aquariums.
