Iskandaria is a genus of stone loaches from the mountain river systems of Central Asia, recorded in the atlas from Afghanistan, Tajikistan, and Uzbekistan - the upper Amu Darya drainage and its tributary valleys through the Pamir and Alai ranges. Like other nemacheilid loaches, Iskandaria species are small, elongate, bottom-hugging fish with a flattened belly, reduced or absent scales, and barbels around a downturned mouth suited to picking invertebrates and detritus from gravel substrate in cold, fast-flowing water. The genus name likely echoes "Iskander," the Central Asian rendering of Alexander, a common element in place names across the region where these loaches occur.
The two species in the atlas, Iskandaria kuschakewitschi (the Kuschakewitsch loach) and I. pardalis (the Tajik loach), run from about 2.5–5.5 in and are essentially unknown in the aquarium hobby - they belong to the large, taxonomically active world of Central Asian nemacheilid loaches that remains of far more interest to regional ichthyologists than to fishkeepers. Both are currently assessed as Least Concern, though that status likely reflects limited fishing and collection pressure on remote mountain streams as much as any thorough population survey.
