Can Amazon Leaf Fish and Xenotilapia papilio Live Together?

Amazon Leaf Fish is a peaceful species (2/10), while Xenotilapia papilio is moderately assertive (6/10). This notable difference means Xenotilapia papilio may occasionally assert dominance over Amazon Leaf Fish.

In terms of spatial distribution, Amazon Leaf Fish prefers the Middle (Open Water) and Top (Surface) zones, whereas Xenotilapia papilio occupies the Bottom (Substrate) zone. Because they use different levels of the water column, territorial disputes are less likely and the tank will appear more balanced.

Worth noting: Amazon Leaf Fish is nocturnal and will be most active after lights-out, naturally reducing daytime encounters.

The safe temperature window for both species falls between 23°C and 28°C. Aim for the midpoint of this range (around 25.5°C) for optimal comfort.

The pH requirements of Amazon Leaf Fish (5–6.8) and Xenotilapia papilio (7.8–9) do not overlap, making it impossible to satisfy both species simultaneously.

Hardness requirements are incompatible: Amazon Leaf Fish needs 0–8 dGH while Xenotilapia papilio requires 10–25 dGH.

To house Amazon Leaf Fish and Xenotilapia papilio together, plan for an aquarium of at least 110 litres with a minimum length of 90 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: Leaf Litter/Blackwater, Plants - Densely covered, Driftwood (Digestion/Hiding), Plants - Floating, Sand (Sifters), Smooth Gravel (Sensitive Barbels). Meeting these requirements will help both species thrive.

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

Amazon Leaf Fish and Xenotilapia papilio 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.
