Can Leopard Bushfish (Ctenopoma) and Malawi Hawk Live Together?
Leopard Bushfish (Ctenopoma) 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.
At a Glance
Can your tank handle Leopard Bushfish (Ctenopoma) 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
Leopard Bushfish (Ctenopoma) is a generally mild-mannered species (4/10), while Malawi Hawk is semi-aggressive (7/10). This modest difference means Malawi Hawk may occasionally assert dominance over Leopard Bushfish (Ctenopoma).
Leopard Bushfish (Ctenopoma) 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.
Worth noting: Leopard Bushfish (Ctenopoma) is nocturnal and will be most active after lights-out, naturally reducing daytime encounters.
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 Leopard Bushfish (Ctenopoma) (6–7.5) 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 10–15 dGH. Regular testing will ensure conditions stay within this range.

Tank Setup
To house Leopard Bushfish (Ctenopoma) 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: Driftwood (Digestion/Hiding), Plants - Densely covered, Plants - Floating, Leaf Litter/Blackwater, Sand (Sifters). 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.
Suitable Tank Sizes
Standard aquarium sizes large enough for both Leopard Bushfish (Ctenopoma) and Malawi Hawk.

Frequently Asked Questions
Can Leopard Bushfish (Ctenopoma) 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 Leopard Bushfish (Ctenopoma) 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 Leopard Bushfish (Ctenopoma) 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 Leopard Bushfish (Ctenopoma) or Malawi Hawk aggressive?
Leopard Bushfish (Ctenopoma) is generally mild-mannered (4/10) and Malawi Hawk is semi-aggressive (7/10). Their similar temperaments generally lead to a peaceful coexistence.
What pH do Leopard Bushfish (Ctenopoma) and Malawi Hawk need?
Their pH requirements do not overlap. Leopard Bushfish (Ctenopoma) prefers 6–7.5, 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.
Does Leopard Bushfish (Ctenopoma) being nocturnal affect compatibility?
Leopard Bushfish (Ctenopoma) is most active after lights-out, which naturally reduces daytime encounters with its tank mate. This can actually be beneficial, as both fish get undisturbed time to feed and explore. Just ensure food reaches Leopard Bushfish (Ctenopoma) during evening hours.
