Can Silver Tiger Perch (American Tigerfish) and Teacup Stingray (Common Freshwater Ray) Live Together?

Silver Tiger Perch (American Tigerfish) is a semi-aggressive species (7/10), while Teacup Stingray (Common Freshwater Ray) is moderately assertive (6/10). This modest difference means Silver Tiger Perch (American Tigerfish) may occasionally assert dominance over Teacup Stingray (Common Freshwater Ray).

Silver Tiger Perch (American Tigerfish) and Teacup Stingray (Common Freshwater Ray) 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 24°C and 28°C. Aim for the midpoint of this range (around 26.0°C) for optimal comfort.

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

Hardness requirements are incompatible: Silver Tiger Perch (American Tigerfish) needs 15–30 dGH while Teacup Stingray (Common Freshwater Ray) requires 1–12 dGH.

To house Silver Tiger Perch (American Tigerfish) and Teacup Stingray (Common Freshwater Ray) together, plan for an aquarium of at least 750 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: Driftwood (Digestion/Hiding), 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.
