Can Loxozonus Corydoras (C079/C082) and Yellow Lab (Mbuna) Live Together?

Loxozonus Corydoras (C079/C082) is a peaceful species (0/10), while Yellow Lab (Mbuna) is moderately assertive (6/10). This notable difference means Yellow Lab (Mbuna) may occasionally assert dominance over Loxozonus Corydoras (C079/C082).

Large aggression gap (6 points) between Loxozonus Corydoras (C079/C082) and Yellow Lab (Mbuna) increases stress risk for the more peaceful fish.

Loxozonus Corydoras (C079/C082) and Yellow Lab (Mbuna) both frequent the Bottom (Substrate) region of the setup. This overlap can increase competition for space, so providing ample room and cover is important to keep both species comfortable.

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

The pH requirements of Loxozonus Corydoras (C079/C082) (6–7.2) and Yellow Lab (Mbuna) (7.5–8.8) do not overlap, making it impossible to satisfy both species simultaneously.

For general hardness, the shared comfort zone is 10–12 dGH. Regular testing will ensure conditions stay within this range.

To house Loxozonus Corydoras (C079/C082) and Yellow Lab (Mbuna) together, plan for an aquarium of at least 150 litres with a minimum length of 90 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 low (still water) water movement, so a standard filtration setup rated for the tank volume should suffice.

Loxozonus Corydoras (C079/C082) and Yellow Lab (Mbuna) 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.
