Description

David's hillstream loach is a hillstream loach (Gastromyzontidae) from East Asia. The species has an elongate, flattened body with broad, horizontally spread pectoral and pelvic fins that together form a sucker, with which it clings to stones in strong current. It inhabits fast-flowing, clear mountain streams with a rocky bottom. With its inferior mouth it rasps algae, diatoms and growth from the surface of stones. The species is harmless to humans.
