Chinese Hillstream Loach

Chinese Hillstream Loaches are primarily herbivores that graze constantly on biofilm, algae, and aufwuchs growing on rocks and glass. Supplement their diet with sinking algae wafers, spirulina tablets, blanched zucchini or cucumber, and occasional small sinking pellets. Feed once or twice daily, ensuring food reaches the bottom and that there is sufficient biofilm growth in the tank.

These loaches are active, curious fish that spend most of their time clinging to and crawling over rocks, glass, and driftwood in search of biofilm and algae. They are generally peaceful but males can be mildly territorial with one another, so providing ample space and visual breaks reduces conflict. They thrive in groups of three or more and are most active in well-oxygenated, high-flow environments.

Breeding in captivity is possible but considered moderately challenging, requiring very clean, highly oxygenated water with strong flow and a mature tank rich in biofilm. Males will court females by nudging and following them, and eggs are deposited in fine substrate or gravel crevices. The fry are tiny and require infusoria or very fine foods initially, making successful rearing difficult.
