Can Red Goldflake Shrimp and Rosy Red Minnow / Fathead Minnow Live Together?

Red Goldflake Shrimp is a peaceful species (0/10), while Rosy Red Minnow / Fathead Minnow is peaceful (1/10). This modest difference means Rosy Red Minnow / Fathead Minnow may occasionally assert dominance over Red Goldflake Shrimp.

In terms of spatial distribution, Red Goldflake Shrimp prefers the Bottom (Substrate) zone, whereas Rosy Red Minnow / Fathead Minnow occupies the Top (Surface) and Middle (Open Water) zones. Because they use different levels of the water column, territorial disputes are less likely and the tank will appear more balanced.

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 Rosy Red Minnow / Fathead Minnow (10–24°C). This fundamental mismatch makes long-term cohabitation impractical.

Both fish can tolerate a pH between 7.5 and 8. 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 Rosy Red Minnow / Fathead Minnow together, plan for an aquarium of at least 75 litres with a minimum length of 60 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). Meeting these requirements will help both species thrive.

Both species do well with low (still water) water movement, so a standard filtration setup rated for the tank volume should suffice.

Red Goldflake Shrimp and Rosy Red Minnow / Fathead Minnow 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.
