Reticulated Hillstream Loach
The reticulated hillstream loach, also known as the butterfly hillstream loach, is native to cool, fast-moving streams where it feeds on small crustaceans and biofilm that forms on smooth stones.
To thrive, this species requires a well-mimicked natural habitat with soft sand, large smooth stones, a gentle current, very clean water, and high oxygen levels. A filter with a turnover rate of at least 15–20 times per hour is recommended to maintain water quality.
These omnivorous fish need a varied diet including biofilm, algae, worms, and small crustaceans to avoid malnutrition. A tight-fitting lid is essential because their flat body shape acts like a suction cup, allowing them to climb glass and escape the tank.

The fish is active and curious. I provided soft sand, smooth stones, and a good filter with strong water flow. It enjoys the biofilm and small algae. The tank lid is a must—without it, it would have escaped. Very happy with the purchase.

They adapt well to the tank setup. I feed them a mix of algae wafers and frozen worms. The water needs regular maintenance, but the fish stay healthy and active. A tight lid is critical—don’t skip it.

This loach is beautiful and active. The current in the tank keeps it engaged. I added a few small stones and soft sand. It eats biofilm and algae regularly. Very satisfied with the quality and care instructions.
