Freshwater Fish
Hillstream Loach.
The reticulated hillstream loach (Sewellia lineolata) is native to fast-flowing streams in Vietnam and has a flattened, sucker-like body that lets it grip rocks in strong current.
We keep this species at our Erie store. Come and see it in the tanks, or call (814) 456-9445 and ask what we have in right now.

We never ship fish, coral, or invertebrates — every animal here is one you meet in person. Each one is acclimated and health-checked in-house before it goes out into the display tanks. This is a species we keep, and what is swimming on any given day changes with the deliveries, so please call (814) 456-9445 before you drive in.

Good tank mates
Compatibility depends on the individual and the setup, so call us for pairing advice. In general these are gentle, bottom-clinging fish that suit cool, fast-flowing, well-oxygenated tanks, so any tankmates should share those conditions; we're happy to help match them to your tank.

White Cloud Mountain Minnow
A cool-water schooling fish (60–72°F) whose temperature and peaceful temperament align closely with hillstream loach requirements. Both species appreciate high-flow, well-oxygenated water, making them one of the most frequently recommended pairings in the hobby. Best kept at 68–72°F where both species are comfortable.

Zebra Danio
Temperature range (65–77°F) overlaps broadly with the hillstream loach's 68–75°F sweet spot, and zebra danios actively thrive in strong current and highly oxygenated water — the exact conditions hillstream loaches require. Peaceful schooler with no fin-nipping or predation risk toward the loach.

Colored Shrimp
Temperature range (65–75°F) maps directly onto the hillstream loach's requirements. Hillstream loaches are strict biofilm and algae grazers with small, suction-adapted mouths — they are not shrimp predators. Multiple aquarium sources and hobbyist reports confirm successful coexistence. Provide ample cover and flow baffles for shrimplets as a precaution.
- N
Nerite Snail
Peaceful algae-grazing snail that handles clean, well-oxygenated, high-flow water without issue. Occupies a different niche than the loach (glass and hardscape surfaces vs. rock substrate) so there is no meaningful territory conflict. Zero aggression.
