A specialist stream loach for mature river-style aquariums. Red Hillstream Loach needs high oxygen, steady current, clean water and established biofilm grazing surfaces.

Red Hillstream Loach (Homaloptera orthogoniata) is a specialist stream fish for aquarists who can provide clean, fast, oxygen-rich water. It should not be treated as a generic algae cleaner; it is a river-style loach that uses smooth stones, wood and mature biofilm to feel secure and feed naturally.

Use strong filtration, extra aeration and rounded stones that grow grazing film. Keep nitrates low and avoid warm, slow, low-oxygen community tanks. A small group settles better than a lone fish when the aquarium has enough feeding surfaces.
Order with clear care guidance. Livestock is packed for a licensed live-animal courier and covered by our Live Arrival Guarantee when the acclimation guidance is followed.
