Can African Pike and Malawi Eyebiter Live Together?

Not Recommended

African Pike and Malawi Eyebiter 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 African Pike and Malawi Eyebiter?

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

African Pike is a semi-aggressive species (7/10), while Malawi Eyebiter is semi-aggressive (8/10). This modest difference means Malawi Eyebiter may occasionally assert dominance over African Pike.

Both African Pike and Malawi Eyebiter are highly aggressive, increasing the risk of violent confrontations.

African Pike and Malawi Eyebiter both frequent the Top (Surface) and 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.

Worth noting: African Pike is a known jumper, so a tight-fitting lid is essential.

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 African Pike (6–7.5) and Malawi Eyebiter (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 African Pike and Malawi Eyebiter together, plan for an aquarium of at least 680 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: Plants - Floating, Smooth Gravel (Sensitive Barbels), Driftwood (Digestion/Hiding), Sand (Sifters), Plants - Densely covered. 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 African Pike and Malawi Eyebiter.

Frequently Asked Questions

Can African Pike and Malawi Eyebiter live together?

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

What size tank do African Pike and Malawi Eyebiter need?

A minimum of 680 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 African Pike and Malawi Eyebiter 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 African Pike or Malawi Eyebiter aggressive?

African Pike is semi-aggressive (7/10) and Malawi Eyebiter is semi-aggressive (8/10). Their similar temperaments generally lead to a peaceful coexistence.

What pH do African Pike and Malawi Eyebiter need?

Their pH requirements do not overlap. African Pike prefers 6–7.5, while Malawi Eyebiter needs 7.8–8.6. This makes them incompatible in the same water chemistry.
