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

Reticulated Stingray (Teacup Ray) is a generally mild-mannered species (4/10), while Silver Tiger Perch (American Tigerfish) is semi-aggressive (7/10). This modest difference means Silver Tiger Perch (American Tigerfish) may occasionally assert dominance over Reticulated Stingray (Teacup Ray).

Reticulated Stingray (Teacup Ray) 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 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: Reticulated Stingray (Teacup Ray) needs 1–10 dGH while Silver Tiger Perch (American Tigerfish) requires 15–30 dGH.

To house Reticulated Stingray (Teacup Ray) and Silver Tiger Perch (American Tigerfish) together, plan for an aquarium of at least 680 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), 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.

Reticulated Stingray (Teacup Ray) and Silver Tiger Perch (American Tigerfish) 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.
