Can African Pike and Teacup Stingray (Common Freshwater Ray) Live Together?

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

In terms of spatial distribution, African Pike prefers the Top (Surface) and Middle (Open Water) zones, whereas Teacup Stingray (Common Freshwater Ray) occupies the Bottom (Substrate) zone. Because they use different levels of the water column, territorial disputes are less likely and the tank will appear more balanced.

Worth noting: African Pike is a known jumper, so a tight-fitting lid is essential.

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 6 and 7.5. Maintaining a stable value within this band is more important than hitting an exact number.

For general hardness, the shared comfort zone is 4–12 dGH. Regular testing will ensure conditions stay within this range.

To house African Pike 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.

Because this pairing requires extra vigilance, include plenty of hiding spots — caves, driftwood, and dense plant clusters — so the less dominant fish can retreat when needed.

Specific environmental needs for this combination include: Plants - Floating, Smooth Gravel (Sensitive Barbels), Driftwood (Digestion/Hiding), Sand (Sifters). 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.
