Description

The reticulated hillstream loach is a hillstream loach (Gastromyzontidae) from Southeast Asia. The species has a flattened body with broad, horizontally spread pectoral and pelvic fins that together form a sucker, with which it clings to stones in fast-flowing water. Its body bears a fine net-like tiger pattern. It lives in rapids and riffles of small, clear mountain streams and rasps algae and growth from the stones. Through habitat loss it is considered vulnerable. The species is harmless to humans.
