Can Apistogramma atahualpa and Nyererei Victorian Cichlid Live Together?

Apistogramma atahualpa is a generally mild-mannered species (4/10), while Nyererei Victorian Cichlid is semi-aggressive (7/10). This modest difference means Nyererei Victorian Cichlid may occasionally assert dominance over Apistogramma atahualpa.

Apistogramma atahualpa and Nyererei Victorian Cichlid 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: Aggressive fish may bully and stress shy, slow-moving species. 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 27°C. Aim for the midpoint of this range (around 25.5°C) for optimal comfort.

The pH requirements of Apistogramma atahualpa (4.5–6.5) and Nyererei Victorian Cichlid (7.4–8.6) do not overlap, making it impossible to satisfy both species simultaneously.

Hardness requirements are incompatible: Apistogramma atahualpa needs 0–5 dGH while Nyererei Victorian Cichlid requires 8–20 dGH.

To house Apistogramma atahualpa and Nyererei Victorian Cichlid 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. Meeting these requirements will help both species thrive.

Note a potential conflict in setup requirements: Nyererei Victorian Cichlid is a plant destroyer, which conflicts with Apistogramma atahualpa'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 atahualpa and Nyererei Victorian Cichlid 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.
