Freshwater Algae Grazer • Peaceful Bottom Dweller • High-Flow Specialist • Stream-Dwelling Loach
📋 The Tiger Hillstream Loach (Sewellia lineolata) is a uniquely shaped freshwater loach adapted to fast-flowing mountain streams, recognized by its striking tiger-striped pattern and flattened body.
It thrives as a Peaceful Bottom Dweller, spending most of its time clinging to rocks and glass in search of biofilm and algae.
Unlike typical loaches, it requires strong water movement and high oxygen levels, making it a true High-Flow Specialist.
