Can Andinoacara sp. Gold Saum and Apistogramma uaupesi Live Together?

Andinoacara sp. Gold Saum is a semi-aggressive species (8/10), while Apistogramma uaupesi is moderately assertive (5/10). This modest difference means Andinoacara sp. Gold Saum may occasionally assert dominance over Apistogramma uaupesi.

Andinoacara sp. Gold Saum and Apistogramma uaupesi 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. Two territorial species may clash over territory, especially in smaller tanks.

The safe temperature window for both species falls between 24°C and 25°C. Aim for the midpoint of this range (around 24.5°C) for optimal comfort.

The pH requirements of Andinoacara sp. Gold Saum (6.5–8) and Apistogramma uaupesi (4–6) do not overlap, making it impossible to satisfy both species simultaneously.

For general hardness, the shared comfort zone is 5–5 dGH. Regular testing will ensure conditions stay within this range.

To house Andinoacara sp. Gold Saum and Apistogramma uaupesi together, plan for an aquarium of at least 250 litres with a minimum length of 120 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), Smooth Gravel (Sensitive Barbels), Leaf Litter/Blackwater, Plants - Densely covered. Meeting these requirements will help both species thrive.

Note a potential conflict in setup requirements: Andinoacara sp. Gold Saum 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 moderate (standard) water movement, so a standard filtration setup rated for the tank volume should suffice.

Andinoacara sp. Gold Saum and Apistogramma uaupesi 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.
