About
Hemimyzon nanensis is a uncommonly available hillstream loach from the upland tributaries of northern Thailand, displaying a warm tan base colour with rich dark brown spotting. It demands pristine, cool and highly oxygenated water to thrive, and is best suited to advanced hillstream aquarists with well-established high-flow systems. Rewarding in the right conditions, it will display active grazing and courtship behaviour.
