Sahyadria

Sahyadria chalakkudiensis is a cyprinid from Kerala, southern India, known from the Chalakudy, Periyar, Pamba and Achankovil rivers. It was first exported in 1996 under the name S. denisonii, from which it differs in its inferior mouth, a black marking in the dorsal fin, and a duller scarlet body stripe. It can be belligerent and is unsuitable for the general community aquarium.

The red-line torpedo barb, Sahyadria denisonii, is a cyprinid endemic to Kerala and Karnataka in southern India. Extremely popular since it appeared in the trade in the late 1990s, it is listed as Endangered by the IUCN, and collection for the aquarium trade has been held largely responsible for its decline. Large numbers are produced in Southeast Asia and Eastern Europe. The similar S. chalakkudiensis is occasionally traded as this species and is more belligerent.
