Hillstream Loach (Gastromyzon sp.) for Sale in Canada

The Hillstream Loach (Gastromyzon sp.), available under stock code 2401, is a unique freshwater loach admired for its flattened body, striking patterns, and remarkable ability to cling to rocks in fast-flowing streams. Native to the mountain rivers of Borneo and Southeast Asia, this fascinating species is an excellent choice for aquarists who enjoy natural river biotope aquariums and peaceful community fish.

Unlike most loaches, Hillstream Loaches use specially adapted fins that function like suction cups, allowing them to attach firmly to rocks, driftwood, and aquarium glass even in strong currents. Their constant grazing on algae and biofilm makes them both attractive and beneficial additions to mature freshwater aquariums.

Monster Aquarium Canada proudly offers healthy Hillstream Loach (Gastromyzon sp.) with professional live fish shipping throughout Canada.
