Can Adolfo Cory and Three-Spot Torpedo Hap Live Together?

Adolfo Cory is a peaceful species (1/10), while Three-Spot Torpedo Hap is moderately assertive (6/10). This notable difference means Three-Spot Torpedo Hap may occasionally assert dominance over Adolfo Cory.

Adolfo Cory and Three-Spot Torpedo Hap 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.

The safe temperature window for both species falls between 23°C and 26°C. Aim for the midpoint of this range (around 24.5°C) for optimal comfort.

The pH requirements of Adolfo Cory (4–7) and Three-Spot Torpedo Hap (7.5–8.6) do not overlap, making it impossible to satisfy both species simultaneously.

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

To house Adolfo Cory and Three-Spot Torpedo Hap together, plan for an aquarium of at least 570 litres with a minimum length of 180 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), Leaf Litter/Blackwater, 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.

Adolfo Cory and Three-Spot Torpedo Hap 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.
