Can Filament Barb and Orange Peacock Live Together?

Reviewed by Guidarium Editorial DeskUpdated May 7, 2026
Not Recommended

Filament Barb and Orange Peacock 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 Filament Barb and Orange Peacock?

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

Filament Barb is a generally mild-mannered species (4/10), while Orange Peacock is moderately assertive (6/10). This modest difference means Orange Peacock may occasionally assert dominance over Filament Barb.

Filament Barb and Orange 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.

Worth noting: Filament Barb is a known jumper, so a tight-fitting lid is essential.

Water Parameters

The safe temperature window for both species falls between 24°C and 26°C. Aim for the midpoint of this range (around 25.0°C) for optimal comfort.

The pH requirements of Filament Barb (6–7.5) and Orange Peacock (7.8–8.6) do not overlap, making it impossible to satisfy both species simultaneously.

For general hardness, the shared comfort zone is 10–15 dGH. Regular testing will ensure conditions stay within this range.

Tank Setup

To house Filament Barb and Orange Peacock together, plan for an aquarium of at least 240 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: Smooth Gravel (Sensitive Barbels), Driftwood (Digestion/Hiding), Sand (Sifters). Meeting these requirements will help both species thrive.

Both species do well with high (river/stream) water movement, so a standard filtration setup rated for the tank volume should suffice.

Why This Pairing Usually Fails in Practice

Filament Barb and Orange 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.

Frequently Asked Questions

Can Filament Barb and Orange Peacock live together?

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

What size tank do Filament Barb and Orange Peacock need?

A minimum of 240 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 Filament Barb and Orange Peacock together?

Keep the aquarium between 24°C and 26°C. A target of around 25.0°C sits comfortably within both species' preferred ranges.

Are Filament Barb or Orange Peacock aggressive?

Filament Barb is generally mild-mannered (4/10) and Orange Peacock is moderately assertive (6/10). Their similar temperaments generally lead to a peaceful coexistence.

What pH do Filament Barb and Orange Peacock need?

Their pH requirements do not overlap. Filament Barb prefers 6–7.5, while Orange Peacock needs 7.8–8.6. This makes them incompatible in the same water chemistry.

Will Filament Barb nip Orange Peacock's fins?

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