Can Buccochromis lepturus and Uaru Live Together?

Buccochromis lepturus is a moderately assertive species (6/10), while Uaru is generally mild-mannered (4/10). This modest difference means Buccochromis lepturus may occasionally assert dominance over Uaru.

Buccochromis lepturus and Uaru both frequent the Middle (Open Water) and 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.

Additional behavioural considerations to keep in mind: Hyperactive swimmers can stress shy, slow-moving species through constant motion.

The safe temperature window for both species falls between 27°C and 28°C. Aim for the midpoint of this range (around 27.5°C) for optimal comfort.

The pH requirements of Buccochromis lepturus (7.5–8.8) and Uaru (5–7) do not overlap, making it impossible to satisfy both species simultaneously.

Hardness requirements are incompatible: Buccochromis lepturus needs 10–25 dGH while Uaru requires 1–8 dGH.

To house Buccochromis lepturus and Uaru together, plan for an aquarium of at least 560 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), 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.

Buccochromis lepturus and Uaru 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.
