Can Malawi Eyebiter and Tire Track Eel Live Together?

Malawi Eyebiter is a semi-aggressive species (8/10), while Tire Track Eel is moderately assertive (6/10). This modest difference means Malawi Eyebiter may occasionally assert dominance over Tire Track Eel.

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

Worth noting: Tire Track Eel is nocturnal and will be most active after lights-out, naturally reducing daytime encounters. Also, Malawi Eyebiter is a known jumper, so a tight-fitting lid is essential.

The safe temperature window for both species falls between 23°C and 28°C. Aim for the midpoint of this range (around 25.5°C) for optimal comfort.

The pH requirements of Malawi Eyebiter (7.8–8.6) and Tire Track Eel (6.5–7.5) 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.

To house Malawi Eyebiter and Tire Track Eel 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: Sand (Sifters), Plants - Densely covered, 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.

Malawi Eyebiter and Tire Track Eel 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.
