Can your tank handle Fairy Cichlid (Brichardi) and Pike Cichlid (Xingu)?

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

Fairy Cichlid (Brichardi) is a semi-aggressive species (8/10), while Pike Cichlid (Xingu) is highly aggressive (9/10). This modest difference means Pike Cichlid (Xingu) may occasionally assert dominance over Fairy Cichlid (Brichardi).

Both Fairy Cichlid (Brichardi) and Pike Cichlid (Xingu) are highly aggressive, increasing the risk of violent confrontations.

Fairy Cichlid (Brichardi) and Pike Cichlid (Xingu) 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.

Additional behavioural considerations to keep in mind: Two territorial species may clash over territory, especially in smaller tanks. Two aggressive species housed together increases risk of fighting.

Worth noting: Pike Cichlid (Xingu) 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 Fairy Cichlid (Brichardi) (8–9) and Pike Cichlid (Xingu) (6–7.5) do not overlap, making it impossible to satisfy both species simultaneously.

For general hardness, the shared comfort zone is 10–12 dGH. Regular testing will ensure conditions stay within this range.

Tank Setup

To house Fairy Cichlid (Brichardi) and Pike Cichlid (Xingu) together, plan for an aquarium of at least 560 litres with a minimum length of 180 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), Smooth Gravel (Sensitive Barbels), Driftwood (Digestion/Hiding). Meeting these requirements will help both species thrive.

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

Why This Pairing Usually Fails in Practice

Fairy Cichlid (Brichardi) and Pike Cichlid (Xingu) 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.

Suitable Tank Sizes

Standard aquarium sizes large enough for both Fairy Cichlid (Brichardi) and Pike Cichlid (Xingu).

Frequently Asked Questions

Can Fairy Cichlid (Brichardi) and Pike Cichlid (Xingu) live together?

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

What size tank do Fairy Cichlid (Brichardi) and Pike Cichlid (Xingu) need?

A minimum of 560 litres (tank length at least 180 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 Fairy Cichlid (Brichardi) and Pike Cichlid (Xingu) 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 Fairy Cichlid (Brichardi) or Pike Cichlid (Xingu) aggressive?

Fairy Cichlid (Brichardi) is semi-aggressive (8/10) and Pike Cichlid (Xingu) is highly aggressive (9/10). Their similar temperaments generally lead to a peaceful coexistence.

What pH do Fairy Cichlid (Brichardi) and Pike Cichlid (Xingu) need?

Their pH requirements do not overlap. Fairy Cichlid (Brichardi) prefers 8–9, while Pike Cichlid (Xingu) needs 6–7.5. This makes them incompatible in the same water chemistry.

How do I manage Fairy Cichlid (Brichardi)'s territorial behaviour?

Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives Fairy Cichlid (Brichardi) 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.
