I bought this loach for my high-flow aquarium and it has adapted well. It stays near the rocks and grazes quietly. The pattern is very distinct and it looks natural in the current. Very satisfied with the purchase.

It’s a rare species and hard to find. Once I set up the strong flow and proper oxygenation, it settled in quickly. Feeds on the glass and rocks, no aggression. A nice addition to a mature tank.
