Can Chocolate Gourami and Kiunga Blue Eye Live Together?

Reviewed by Guidarium Editorial DeskUpdated May 6, 2026
Not Recommended

Chocolate Gourami and Kiunga Blue Eye 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 Chocolate Gourami and Kiunga Blue Eye?

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

Chocolate Gourami is a peaceful species (2/10), while Kiunga Blue Eye is peaceful (1/10). This modest difference means Chocolate Gourami may occasionally assert dominance over Kiunga Blue Eye.

Chocolate Gourami and Kiunga Blue Eye both frequent the Top (Surface) and Middle (Open Water) 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.

Worth noting: Kiunga Blue Eye is a known jumper, so a tight-fitting lid is essential.

Water Parameters

The safe temperature window for both species falls between 25°C and 26°C. Aim for the midpoint of this range (around 25.5°C) for optimal comfort.

The pH requirements of Chocolate Gourami (4–6.5) and Kiunga Blue Eye (7–8) do not overlap, making it impossible to satisfy both species simultaneously.

For general hardness, the shared comfort zone is 5–5 dGH. Regular testing will ensure conditions stay within this range.

Tank Setup

To house Chocolate Gourami and Kiunga Blue Eye together, plan for an aquarium of at least 55 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: Leaf Litter/Blackwater, Plants - Densely covered, Plants - Floating, Driftwood (Digestion/Hiding). 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

Chocolate Gourami and Kiunga Blue Eye 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 Chocolate Gourami and Kiunga Blue Eye live together?

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

What size tank do Chocolate Gourami and Kiunga Blue Eye need?

A minimum of 55 litres (tank length at least 60 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 Chocolate Gourami and Kiunga Blue Eye together?

Keep the aquarium between 25°C and 26°C. A target of around 25.5°C sits comfortably within both species' preferred ranges.

Are Chocolate Gourami or Kiunga Blue Eye aggressive?

Chocolate Gourami is peaceful (2/10) and Kiunga Blue Eye is peaceful (1/10). Their similar temperaments generally lead to a peaceful coexistence.

What pH do Chocolate Gourami and Kiunga Blue Eye need?

Their pH requirements do not overlap. Chocolate Gourami prefers 4–6.5, while Kiunga Blue Eye needs 7–8. This makes them incompatible in the same water chemistry.
