Can Red Goldflake Shrimp and Rosy Barb Live Together?

Reviewed by Guidarium Editorial DeskUpdated May 11, 2026
Not Recommended

Red Goldflake Shrimp and Rosy Barb are not recommended as tank mates due to no temperature overlap. Housing these species together is likely to result in stress, health problems, or direct harm to one or both fish.

Can your tank handle Red Goldflake Shrimp and Rosy Barb?

Compatibility is only part of the answer. Test both fish with your real tank size, current stock, and maintenance needs to see if you have enough space and a safe stocking level before you add them.

Behaviour & Temperament

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

Red Goldflake Shrimp and Rosy Barb 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. Aggressive eaters may outcompete shy fish for food, leading to malnutrition.

Water Parameters

There is no temperature overlap between Red Goldflake Shrimp (26–29°C) and Rosy Barb (18–25°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.

Tank Setup

To house Red Goldflake Shrimp and Rosy Barb together, plan for an aquarium of at least 110 litres with a minimum length of 80 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). 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.

Why This Pairing Usually Fails in Practice

Red Goldflake Shrimp and Rosy Barb 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.

Diet & Feeding

Feeding time deserves special attention with this pairing. Rosy Barb is an aggressive eater that may prevent Red Goldflake Shrimp from getting enough food.

Because Rosy Barb is a fast, competitive feeder, consider using sinking pellets or feeding at opposite ends of the setup to ensure Red Goldflake Shrimp receives an adequate share.

Frequently Asked Questions

Can Red Goldflake Shrimp and Rosy Barb live together?

No. This combination is not recommended. Key incompatibilities — such as non-overlapping temperature ranges — make cohabitation unsafe.

What size tank do Red Goldflake Shrimp and Rosy Barb need?

A minimum of 110 litres (tank length at least 80 cm) is recommended. This provides enough space for both species to establish their own areas and reduces the likelihood of territorial disputes.

What water temperature is best for Red Goldflake Shrimp and Rosy Barb together?

Unfortunately, there is no temperature range that satisfies both species. Red Goldflake Shrimp requires 26–29°C, while Rosy Barb needs 18–25°C.

Are Red Goldflake Shrimp or Rosy Barb aggressive?

Red Goldflake Shrimp is peaceful (0/10) and Rosy Barb is generally mild-mannered (3/10). Their similar temperaments generally lead to a peaceful coexistence.

What pH do Red Goldflake Shrimp and Rosy Barb need?

Both species overlap in the 7.5–8 pH range. Consistency is key — avoid sudden swings, and test regularly to stay within this window.

Will Rosy Barb nip Red Goldflake Shrimp's fins?

Rosy Barb is a known fin nipper. If Red Goldflake Shrimp has long or flowing fins, there is a real risk of fin damage. Keeping Rosy Barb in a larger group can help redirect nipping behaviour toward conspecifics.
