Overview
The Devdevi loach is a modest, manageable stone loach for the bottom of a cool hill-stream tank. It suits a keeper with some experience.
Did you know
The Devdevi loach was described by Sunder Lal Hora, the great chronicler of India's hill-stream fishes. Hora built a famous idea from fishes like this one, the Satpura hypothesis. It argues that hill-stream animals spread across India along old mountain chains.
Caring for the Devdevi loach
Keep a handful of Devdevi loaches together in a tank of 20 gal (75 L) or more. Lay a stony floor of fine gravel and smooth stones, with rocky cover that breaks up sightlines. Each fish then holds a small territory without much trouble, and the group stays civil and active.
Keep the water cool, clean and moving, at 64 to 75°F (18 to 24°C) and a pH of 6.5 to 7.5. Give it moderate to strong flow and good oxygen, and avoid warm, still conditions.
The Devdevi loach works the bottom for food. Offer small sinking items, frozen daphnia and micro pellets that reach the floor. It is mostly peaceful and suits a cool community of danios and small barbs. Its breeding has not been recorded in the aquarium.
Good to know
Schistura devdevi is a small stone loach with neat, regular barring, in the family Nemacheilidae. It was described in 1935 and named after Dev Dev Mukerji, a young Indian ichthyologist of the same period.
In the wild
The Devdevi loach lives in cool, swift streams of the eastern Himalayan foothills, below Darjeeling and Sikkim in northeast India. These are fresh, moving hill waters that run clear over a pebbly bed.
