Can Hi Fin Peppered Cory and Livingston's Cichlid Live Together?

Hi Fin Peppered Cory is a peaceful species (2/10), while Livingston's Cichlid is semi-aggressive (8/10). This notable difference means Livingston's Cichlid may occasionally assert dominance over Hi Fin Peppered Cory.

Large aggression gap (6 points) between Hi Fin Peppered Cory and Livingston's Cichlid increases stress risk for the more peaceful fish.

Hi Fin Peppered Cory and Livingston's Cichlid both frequent the Bottom (Substrate) 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: Hi Fin Peppered Cory 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 23°C. Aim for the midpoint of this range (around 23.0°C) for optimal comfort.

The pH requirements of Hi Fin Peppered Cory (6–7.5) and Livingston's Cichlid (7.6–8.6) do not overlap, making it impossible to satisfy both species simultaneously.

For general hardness, the shared comfort zone is 10–15 dGH. Regular testing will ensure conditions stay within this range.

To house Hi Fin Peppered Cory and Livingston's Cichlid together, plan for an aquarium of at least 470 litres with a minimum length of 150 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), Smooth Gravel (Sensitive Barbels). 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.

Hi Fin Peppered Cory and Livingston's Cichlid 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.
