Can Red Goldflake Shrimp and Reticulated Hillstream Loach Live Together?

Red Goldflake Shrimp is a peaceful species (0/10), while Reticulated Hillstream Loach is generally mild-mannered (3/10). This modest difference means Reticulated Hillstream Loach may occasionally assert dominance over Red Goldflake Shrimp.

Red Goldflake Shrimp and Reticulated Hillstream Loach both frequent the Bottom (Substrate) region of the setup. This overlap can increase competition for space, so providing ample room and cover is important to keep both species comfortable.

Additional behavioural considerations to keep in mind: Hyperactive swimmers can stress shy, slow-moving species through constant motion.

There is no temperature overlap between Red Goldflake Shrimp (26–29°C) and Reticulated Hillstream Loach (20–24°C). This fundamental mismatch makes long-term cohabitation impractical.

Both fish can tolerate a pH between 7.5 and 7.5. Maintaining a stable value within this band is more important than hitting an exact number.

For general hardness, the shared comfort zone is 4–10 dGH. Regular testing will ensure conditions stay within this range.

To house Red Goldflake Shrimp and Reticulated Hillstream Loach together, plan for an aquarium of at least 80 litres with a minimum length of 90 cm. This recommendation combines the stricter species minimums with a community-load allowance so the pairing has realistic long-term space and filtration headroom.

Providing a mix of open swimming space and sheltered areas with rocks, driftwood, or plants will keep both species comfortable and allow natural behaviour.

Specific environmental needs for this combination include: Sand (Sifters), Established Algae (Otocinclus), Smooth Gravel (Sensitive Barbels), Plants - lighly covered. Meeting these requirements will help both species thrive.

Red Goldflake Shrimp prefers Low (Still Water) flow while Reticulated Hillstream Loach needs High (River/Stream) flow. Consider positioning filter outlets and using baffles to create zones of different current intensity within the same tank.

Red Goldflake Shrimp and Reticulated Hillstream Loach are the kind of pair that can look acceptable in a shop but become a maintenance problem at home. The main risk is not a single number in the chart; it is the way incompatible behavior, water needs, or pressure on space compounds over time once both fish are established in the same tank.
