Behaviour & Temperament

Chocolate Gourami is a peaceful species (2/10), while Fort Maguire Peacock is moderately assertive (6/10). This notable difference means Fort Maguire Peacock may occasionally assert dominance over Chocolate Gourami.

Chocolate Gourami and Fort Maguire Peacock both frequent the Middle (Open Water) and 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.

Water Parameters

The safe temperature window for both species falls between 25°C and 28°C. Aim for the midpoint of this range (around 26.5°C) for optimal comfort.

The pH requirements of Chocolate Gourami (4–6.5) and Fort Maguire Peacock (7.8–8.6) do not overlap, making it impossible to satisfy both species simultaneously.

Hardness requirements are incompatible: Chocolate Gourami needs 0–5 dGH while Fort Maguire Peacock requires 10–25 dGH.

Tank Setup

To house Chocolate Gourami and Fort Maguire Peacock together, plan for an aquarium of at least 208 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: Leaf Litter/Blackwater, Plants - Densely covered, Plants - Floating, Driftwood (Digestion/Hiding), Sand (Sifters). 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 Fort Maguire Peacock 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.

Can Chocolate Gourami and Fort Maguire Peacock 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 Fort Maguire Peacock need?

A minimum of 208 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 Chocolate Gourami and Fort Maguire Peacock together?

Keep the aquarium between 25°C and 28°C. A target of around 26.5°C sits comfortably within both species' preferred ranges.

Are Chocolate Gourami or Fort Maguire Peacock aggressive?

Chocolate Gourami is peaceful (2/10) and Fort Maguire Peacock is moderately assertive (6/10). The gap in aggression levels means the calmer fish may experience stress from the more assertive one.

What pH do Chocolate Gourami and Fort Maguire Peacock need?

Their pH requirements do not overlap. Chocolate Gourami prefers 4–6.5, while Fort Maguire Peacock needs 7.8–8.6. This makes them incompatible in the same water chemistry.
