Fish Profiles: Hillstream Loach

Sewellia lineolata, also known as the Tiger Hillstream Loach, is a freshwater fish species native to Vietnam. It is among the most attractive balitorids yet seen, with tubercles on the snout and raised rows of soft, raised, tuberculated tissue on the anterior pectoral rays.

The species is restricted to shallow, fast-flowing, highly-oxygenated headwaters and tributaries characterized by stretches of riffles and runs broken up by pools or cascades in some cases. The fish are typically found in clear, oxygen-saturated water which, allied with the sun, facilitates the development of a rich biofilm carpeting submerged surfaces. The fish can grow up to 55-65mm in length.
