Spotted Hillstream Loach | Butterfly Hillstream Loach
Spotted or Butterfly Hillstream Loaches are some of the most intriguing fish. They are closely related to another fish at Flip Aquatics, the Reticulated Hillstream Loach. Their unique body shape is absolutely stunning. They originate from fast-moving streams, therefore; they prefer good water flow. We house ours using a Matten filter to create flow. The use of a matten filter creates good oxygen content and good flow, although a powerhead would help too.

FAQ
What kind of water flow do Spotted Hillstream Loaches prefer?
Spotted Hillstream Loaches prefer high water flow, as they originate from fast-moving streams. A matten filter or a powerhead is recommended to maintain adequate flow.
Can these loaches be kept in a standard aquarium without additional flow?
No, these loaches require strong water flow. A standard aquarium without supplemental flow, such as a powerhead, may not meet their needs.
Is there a specific filter recommended for housing these fish?
A matten filter is used in our setup to provide both flow and oxygenation. A powerhead can also be added to enhance water movement.

The loach is active and colorful, adding a lot of interest to the tank. I noticed it swims near the back and sides where the flow is stronger. I use a matten filter and it works well. The fish seems healthy after a few weeks.
Mary Watson –
Great fish with a unique appearance. I adjusted the filter to increase flow and now the loach is more active. It’s not aggressive and blends well with other community fish.
Sam Marshall –
I was impressed by how quickly it adapted to the tank. The flow from the matten filter is sufficient, and the fish stays near the surface. Very active and curious.
