Behaviour & Temperament

Cockatoo Dwarf Cichlid is a moderately assertive species (5/10), while Fort Maguire Peacock is moderately assertive (6/10). This modest difference means Fort Maguire Peacock may occasionally assert dominance over Cockatoo Dwarf Cichlid.

Cockatoo Dwarf Cichlid and Fort Maguire Peacock both frequent the 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 24°C and 28°C. Aim for the midpoint of this range (around 26.0°C) for optimal comfort.

The pH requirements of Cockatoo Dwarf Cichlid (6–7.5) and Fort Maguire Peacock (7.8–8.6) do not overlap, making it impossible to satisfy both species simultaneously.

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

Tank Setup

To house Cockatoo Dwarf Cichlid 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: Sand (Sifters), Driftwood (Digestion/Hiding), Leaf Litter/Blackwater. 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

Cockatoo Dwarf Cichlid 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.

What size tank do Cockatoo Dwarf Cichlid 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 Cockatoo Dwarf Cichlid and Fort Maguire Peacock together?

Keep the aquarium between 24°C and 28°C. A target of around 26.0°C sits comfortably within both species' preferred ranges.

Are Cockatoo Dwarf Cichlid or Fort Maguire Peacock aggressive?

Cockatoo Dwarf Cichlid is moderately assertive (5/10) and Fort Maguire Peacock is moderately assertive (6/10). Their similar temperaments generally lead to a peaceful coexistence.

What pH do Cockatoo Dwarf Cichlid and Fort Maguire Peacock need?

Their pH requirements do not overlap. Cockatoo Dwarf Cichlid prefers 6–7.5, while Fort Maguire Peacock needs 7.8–8.6. This makes them incompatible in the same water chemistry.

How do I manage Cockatoo Dwarf Cichlid's territorial behaviour?

Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives Cockatoo Dwarf Cichlid space to claim a territory without encroaching on the other fish's area. Adding décor that divides the tank into distinct zones works especially well.
