Gastromyzon punctulatus
The Hillstream loach (Gastromyzon punctulatus) is a tiny, rheophilic freshwater catfish native to fast‑flowing mountain streams of Borneo. It clings to rocks using its flattened body and is prized by aquarists rather than anglers, making it a niche target for specialist anglers.
