Can Red Goldflake Shrimp and Redline Rasbora Live Together?

Reviewed by Guidarium Editorial DeskUpdated May 11, 2026
Not Recommended

Red Goldflake Shrimp and Redline Rasbora are not recommended as tank mates due to conflicting pH requirements. 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 Redline Rasbora?

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 Redline Rasbora is peaceful (1/10). This modest difference means Redline Rasbora may occasionally assert dominance over Red Goldflake Shrimp.

In terms of spatial distribution, Red Goldflake Shrimp prefers the Bottom (Substrate) zone, whereas Redline Rasbora 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.

Worth noting: Redline Rasbora is a known jumper, so a tight-fitting lid is essential.

Water Parameters

The safe temperature window for both species falls between 26°C and 27°C. Aim for the midpoint of this range (around 26.5°C) for optimal comfort.

The pH requirements of Red Goldflake Shrimp (7.5–8.5) and Redline Rasbora (4–6.8) do not overlap, making it impossible to satisfy both species simultaneously.

For general hardness, the shared comfort zone is 4–8 dGH. Regular testing will ensure conditions stay within this range.

Tank Setup

To house Red Goldflake Shrimp and Redline Rasbora together, plan for an aquarium of at least 80 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), Leaf Litter/Blackwater, Driftwood (Digestion/Hiding), Plants - Densely covered, Plants - Floating. 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 Redline Rasbora 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.

Frequently Asked Questions

Can Red Goldflake Shrimp and Redline Rasbora live together?

No. This combination is not recommended. Key incompatibilities — such as critical behavioural conflicts — make cohabitation unsafe.

What size tank do Red Goldflake Shrimp and Redline Rasbora need?

A minimum of 80 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 Redline Rasbora together?

Keep the aquarium between 26°C and 27°C. A target of around 26.5°C sits comfortably within both species' preferred ranges.

Are Red Goldflake Shrimp or Redline Rasbora aggressive?

Red Goldflake Shrimp is peaceful (0/10) and Redline Rasbora is peaceful (1/10). Their similar temperaments generally lead to a peaceful coexistence.

What pH do Red Goldflake Shrimp and Redline Rasbora need?

Their pH requirements do not overlap. Red Goldflake Shrimp prefers 7.5–8.5, while Redline Rasbora needs 4–6.8. This makes them incompatible in the same water chemistry.
