Can Adolfo Cory and Silver Tiger Perch (American Tigerfish) Live Together?

Adolfo Cory is a peaceful species (1/10), while Silver Tiger Perch (American Tigerfish) is semi-aggressive (7/10). This notable difference means Silver Tiger Perch (American Tigerfish) may occasionally assert dominance over Adolfo Cory.

Large aggression gap (6 points) between Adolfo Cory and Silver Tiger Perch (American Tigerfish) increases stress risk for the more peaceful fish.

Adolfo Cory and Silver Tiger Perch (American Tigerfish) 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 20°C and 26°C. Aim for the midpoint of this range (around 23.0°C) for optimal comfort.

The pH requirements of Adolfo Cory (4–7) and Silver Tiger Perch (American Tigerfish) (7.5–9) do not overlap, making it impossible to satisfy both species simultaneously.

Hardness requirements are incompatible: Adolfo Cory needs 1–10 dGH while Silver Tiger Perch (American Tigerfish) requires 15–30 dGH.

To house Adolfo Cory and Silver Tiger Perch (American Tigerfish) together, plan for an aquarium of at least 650 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), Driftwood (Digestion/Hiding). 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.
