Can Cupid Cichlid and Malawi Hawk Live Together?

Reviewed by Guidarium Editorial DeskUpdated May 4, 2026
Not Recommended

Cupid Cichlid and Malawi Hawk are not recommended as tank mates due to conflicting pH requirements and incompatible hardness ranges. Housing these species together is likely to result in stress, health problems, or direct harm to one or both fish.

Can your tank handle Cupid Cichlid and Malawi Hawk?

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

Cupid Cichlid is a generally mild-mannered species (3/10), while Malawi Hawk is semi-aggressive (7/10). This notable difference means Malawi Hawk may occasionally assert dominance over Cupid Cichlid.

Cupid Cichlid and Malawi Hawk both frequent the 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: Aggressive fish may bully and stress shy, slow-moving species. Hyperactive swimmers can stress shy, slow-moving species through constant motion.

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 Cupid Cichlid (5–7) and Malawi Hawk (7.8–8.6) do not overlap, making it impossible to satisfy both species simultaneously.

Hardness requirements are incompatible: Cupid Cichlid needs 1–8 dGH while Malawi Hawk requires 10–25 dGH.

Tank Setup

To house Cupid Cichlid and Malawi Hawk together, plan for an aquarium of at least 475 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), 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

Cupid Cichlid and Malawi Hawk 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 Cupid Cichlid and Malawi Hawk.

Frequently Asked Questions

Can Cupid Cichlid and Malawi Hawk live together?

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

What size tank do Cupid Cichlid and Malawi Hawk need?

A minimum of 475 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 Cupid Cichlid and Malawi Hawk 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 Cupid Cichlid or Malawi Hawk aggressive?

Cupid Cichlid is generally mild-mannered (3/10) and Malawi Hawk is semi-aggressive (7/10). The gap in aggression levels means the calmer fish may experience stress from the more assertive one.

What pH do Cupid Cichlid and Malawi Hawk need?

Their pH requirements do not overlap. Cupid Cichlid prefers 5–7, while Malawi Hawk needs 7.8–8.6. This makes them incompatible in the same water chemistry.

How do I manage Malawi Hawk's territorial behaviour?

Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives Malawi Hawk 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.
