Can African Butterfly Fish and Amazon Leaf Fish Live Together?

African Butterfly Fish is a moderately assertive species (5/10), while Amazon Leaf Fish is peaceful (2/10). This modest difference means African Butterfly Fish may occasionally assert dominance over Amazon Leaf Fish.

African Butterfly Fish and Amazon Leaf Fish both frequent the Top (Surface) region of the setup. This overlap can increase competition for space, so providing ample room and cover is important to keep both species comfortable.

Worth noting: African Butterfly Fish is nocturnal and will be most active after lights-out, naturally reducing daytime encounters. Also, African Butterfly Fish is a known jumper, so a tight-fitting lid is essential.

The safe temperature window for both species falls between 24°C and 29°C. Aim for the midpoint of this range (around 26.5°C) for optimal comfort.

Both fish can tolerate a pH between 6 and 6.8. Maintaining a stable value within this band is more important than hitting an exact number.

For general hardness, the shared comfort zone is 1–8 dGH. Regular testing will ensure conditions stay within this range. An aquarium test kit is recommended for monitoring.

To house African Butterfly Fish and Amazon Leaf Fish together, plan for an aquarium of at least 96 litres with a minimum length of 80 cm. This accounts for the larger species' space requirements with an additional 20 % buffer to reduce territorial tension.

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: Plants - Floating, Leaf Litter/Blackwater, Plants - Densely covered, Driftwood (Digestion/Hiding). 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.
