Hemimyzon formosanus is a balitorid loach endemic to Taiwan, most abundant in rivers draining the western slopes of the Central Mountain Range. Current knowledge suggests it is the most widely distributed of the three Hemimyzon species endemic to the island. It lives in shallow, fast-flowing, highly oxygenated headwaters and needs clean, well-oxygenated water, a biologically mature tank with plenty of biofilm, and a tight cover since it can climb glass.
