Hillstream Loach
The regular butterfly loach, or Chinese hillstream loach, has a narrower body than the reticulated hillstream loach. The color pattern is subtly light-banded. 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 hillstream loach is a beautiful addition to my aquarium. It’s active and stays near the rocks where the current flows. I’ve kept it with other peaceful fish and it hasn’t shown any aggression. Feeding is easy with a mix of flakes and frozen foods.

It’s a striking fish with a unique appearance. I noticed it’s more active in the morning and tends to hang out near the back of the tank. The water flow needs to be strong, but once set up, it’s very easy to care for.

I bought this loach for my beginner tank. It’s calm, doesn’t stress other fish, and has a lovely color pattern. The only thing to note is that the tank needs a good flow to keep it happy.
