Can Red Goldflake Shrimp and Turquoise Rainbowfish Live Together?

Reviewed by Guidarium Editorial DeskUpdated May 11, 2026
Not Recommended

Red Goldflake Shrimp and Turquoise Rainbowfish 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 Turquoise Rainbowfish?

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 Turquoise Rainbowfish is peaceful (2/10). This modest difference means Turquoise Rainbowfish may occasionally assert dominance over Red Goldflake Shrimp.

In terms of spatial distribution, Red Goldflake Shrimp prefers the Bottom (Substrate) zone, whereas Turquoise Rainbowfish 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. Aggressive eaters may outcompete shy fish for food, leading to malnutrition.

Worth noting: Turquoise Rainbowfish is a known jumper, so a tight-fitting lid is essential.

Water Parameters

There is no temperature overlap between Red Goldflake Shrimp (26–29°C) and Turquoise Rainbowfish (20–25°C). This fundamental mismatch makes long-term cohabitation impractical.

Both fish can tolerate a pH between 7.5 and 8.5. Maintaining a stable value within this band is more important than hitting an exact number.

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

Tank Setup

To house Red Goldflake Shrimp and Turquoise Rainbowfish together, plan for an aquarium of at least 160 litres with a minimum length of 120 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), Plants - Densely covered, Plants - lighly covered. 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 Turquoise Rainbowfish 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. Turquoise Rainbowfish is an aggressive eater that may prevent Red Goldflake Shrimp from getting enough food.

Because Turquoise Rainbowfish 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 Turquoise Rainbowfish 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 Turquoise Rainbowfish need?

A minimum of 160 litres (tank length at least 120 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 Turquoise Rainbowfish together?

Unfortunately, there is no temperature range that satisfies both species. Red Goldflake Shrimp requires 26–29°C, while Turquoise Rainbowfish needs 20–25°C.

Are Red Goldflake Shrimp or Turquoise Rainbowfish aggressive?

Red Goldflake Shrimp is peaceful (0/10) and Turquoise Rainbowfish is peaceful (2/10). Their similar temperaments generally lead to a peaceful coexistence.

What pH do Red Goldflake Shrimp and Turquoise Rainbowfish need?

Both species overlap in the 7.5–8.5 pH range. Consistency is key — avoid sudden swings, and test regularly to stay within this window.
