Can African Butterfly Fish and Hi Fin Peppered Cory Live Together?

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

In terms of spatial distribution, African Butterfly Fish prefers the Top (Surface) zone, whereas Hi Fin Peppered Cory 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: 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.

There is no temperature overlap between African Butterfly Fish (24–30°C) and Hi Fin Peppered Cory (16–23°C). This fundamental mismatch makes long-term cohabitation impractical.

Both fish can tolerate a pH between 6 and 7.5. Maintaining a stable value within this band is more important than hitting an exact number.

For general hardness, the shared comfort zone is 2–10 dGH. Regular testing will ensure conditions stay within this range.

To house African Butterfly Fish and Hi Fin Peppered Cory together, plan for an aquarium of at least 100 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: 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.
