Can Apistogramma uaupesi and Aurora Yellow Mbuna Live Together?

Apistogramma uaupesi is a moderately assertive species (5/10), while Aurora Yellow Mbuna is semi-aggressive (7/10). This modest difference means Aurora Yellow Mbuna may occasionally assert dominance over Apistogramma uaupesi.

Apistogramma uaupesi and Aurora Yellow 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.

Additional behavioural considerations to keep in mind: Hyperactive swimmers can stress shy, slow-moving species through constant motion. Two territorial species may clash over territory, especially in smaller tanks.

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 Apistogramma uaupesi (4–6) and Aurora Yellow Mbuna (7.5–8.6) do not overlap, making it impossible to satisfy both species simultaneously.

Hardness requirements are incompatible: Apistogramma uaupesi needs 0–5 dGH while Aurora Yellow Mbuna requires 10–25 dGH.

To house Apistogramma uaupesi and Aurora Yellow Mbuna together, plan for an aquarium of at least 271 litres with a minimum length of 100 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, Driftwood (Digestion/Hiding), Plants - Densely covered, Established Algae (Otocinclus). Meeting these requirements will help both species thrive.

Note a potential conflict in setup requirements: Aurora Yellow Mbuna is a plant destroyer, which conflicts with Apistogramma uaupesi's requirement for live plants. Compromise where possible or prioritise the more critical need.

Both species do well with low (still water) water movement, so a standard filtration setup rated for the tank volume should suffice.

Apistogramma uaupesi and Aurora Yellow 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.
