Can Bronze Corydoras and Malawi Hawk Live Together?

Bronze Corydoras 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 Bronze Corydoras.

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

In terms of spatial distribution, Bronze Corydoras 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.

The safe temperature window for both species falls between 24°C and 27°C. Aim for the midpoint of this range (around 25.5°C) for optimal comfort.

The pH requirements of Bronze Corydoras (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.

To house Bronze Corydoras 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). 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.
