Can Adolfo Cory and Malawi Hawk Live Together?

Not Recommended

Adolfo Cory and Malawi Hawk 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 Adolfo Cory 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

Adolfo Cory is a peaceful species (1/10), while Malawi Hawk is semi-aggressive (7/10). This notable difference means Malawi Hawk may occasionally assert dominance over Adolfo Cory.

Large aggression gap (6 points) between Adolfo Cory and Malawi Hawk increases stress risk for the more peaceful fish.

In terms of spatial distribution, Adolfo Cory prefers the Bottom (Substrate) zone, whereas Malawi Hawk occupies the Middle (Open Water) and Top (Surface) zones. Because they use different levels of the water column, territorial disputes are less likely and the tank will appear more balanced.

Water Parameters

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

The pH requirements of Adolfo Cory (4–7) and Malawi Hawk (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 Adolfo Cory 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), Leaf Litter/Blackwater, Smooth Gravel (Sensitive Barbels). 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.

Suitable Tank Sizes

Standard aquarium sizes large enough for both Adolfo Cory and Malawi Hawk.

Frequently Asked Questions

Can Adolfo Cory and Malawi Hawk live together?

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

What size tank do Adolfo Cory 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 Adolfo Cory and Malawi Hawk together?

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

Are Adolfo Cory or Malawi Hawk aggressive?

Adolfo Cory is peaceful (1/10) 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 Adolfo Cory and Malawi Hawk need?

Their pH requirements do not overlap. Adolfo Cory prefers 4–7, 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 dΓ©cor that divides the tank into distinct zones works especially well.
