Can Freshwater Angelfish and Hi Fin Peppered Cory Live Together?

Freshwater Angelfish is a moderately assertive species (6/10), while Hi Fin Peppered Cory is peaceful (2/10). This notable difference means Freshwater Angelfish may occasionally assert dominance over Hi Fin Peppered Cory.

In terms of spatial distribution, Freshwater Angelfish prefers the Middle (Open Water) and Top (Surface) zones, 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: Hi Fin Peppered Cory is nocturnal and will be most active after lights-out, naturally reducing daytime encounters.

There is no temperature overlap between Freshwater Angelfish (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 3–15 dGH. Regular testing will ensure conditions stay within this range.

To house Freshwater Angelfish and Hi Fin Peppered Cory together, plan for an aquarium of at least 150 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 - Densely covered, Driftwood (Digestion/Hiding), Plants - lighly covered, 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.

Freshwater Angelfish and Hi Fin Peppered Cory 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.
