Can Fort Maguire Peacock and German Blue Ram Live Together?

Fort Maguire Peacock is a moderately assertive species (6/10), while German Blue Ram is generally mild-mannered (4/10). This modest difference means Fort Maguire Peacock may occasionally assert dominance over German Blue Ram.

Fort Maguire Peacock and German Blue Ram both frequent the Bottom (Substrate) and Middle (Open Water) 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 27°C and 28°C. Aim for the midpoint of this range (around 27.5°C) for optimal comfort.

The pH requirements of Fort Maguire Peacock (7.8–8.6) and German Blue Ram (5–7) do not overlap, making it impossible to satisfy both species simultaneously.

Hardness requirements are incompatible: Fort Maguire Peacock needs 10–25 dGH while German Blue Ram requires 1–8 dGH.

To house Fort Maguire Peacock and German Blue Ram together, plan for an aquarium of at least 208 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), Plants - Densely covered, Driftwood (Digestion/Hiding), Leaf Litter/Blackwater. 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.

Fort Maguire Peacock and German Blue Ram 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.
