Reticulated Hillstream Loach (3-Pack)
The reticulated butterfly loach, or reticulated hillstream loach, has a broader body than the standard hillstream loach. The most striking feature of this freshwater loach, besides its unusually flat profile, is the fine-line color pattern, called reticulation. Normally hillstream loaches are gathered on rocks of swift-flowing streams in China, and their unusual flat, wide fins are perfectly suited to this environment. Freshwater loaches are hardy and feed on just about anything and are quite the sight hanging on the other side of the aquarium glass.

The loaches are active and colorful, adding a nice dynamic to my tank. They seem to enjoy the rocks and flow, and they don’t stress easily. Great addition to a community aquarium.

They arrived healthy and are now swimming around the tank. The reticulation pattern is very noticeable and adds a unique look. I appreciate the variety in my fish collection.

I bought three for a group tank, and they all seem to get along well. They’re not aggressive and stay near the substrate, which is perfect for a low-maintenance setup.
