Can Kiunga Blue Eye and Raspy River Stingray Live Together?

Kiunga Blue Eye is a peaceful species (1/10), while Raspy River Stingray is generally mild-mannered (4/10). This modest difference means Raspy River Stingray may occasionally assert dominance over Kiunga Blue Eye.

In terms of spatial distribution, Kiunga Blue Eye prefers the Top (Surface) and Middle (Open Water) zones, whereas Raspy River Stingray 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.

There is a critical concern: the Nano / Bite-sized (Predation Risk) behaviour of one fish directly conflicts with the Piscivore (Eats small/nano fish) trait of the other — piscivorous fish will prey on nano-sized tank mates..

Additional behavioural considerations to keep in mind: Shrimp eaters may also prey on very small nano fish.

Worth noting: Kiunga Blue Eye is a known jumper, so a tight-fitting lid is essential.

The safe temperature window for both species falls between 24°C and 26°C. Aim for the midpoint of this range (around 25.0°C) for optimal comfort.

Both fish can tolerate a pH between 7 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 5–10 dGH. Regular testing will ensure conditions stay within this range.

To house Kiunga Blue Eye and Raspy River Stingray together, plan for an aquarium of at least 850 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: Plants - Densely covered, Plants - Floating, Sand (Sifters), Smooth Gravel (Sensitive Barbels). Meeting these requirements will help both species thrive.

Note a potential conflict in setup requirements: Raspy River Stingray is a plant destroyer, which conflicts with Kiunga Blue Eye's requirement for live plants. Compromise where possible or prioritise the more critical need.

Both species do well with low (still water) water movement, so a standard filtration setup rated for the tank volume should suffice.

Kiunga Blue Eye and Raspy River Stingray 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.

Feeding time deserves special attention with this pairing. Raspy River Stingray is a known shrimp eater and may prey on small invertebrates or nano fish like Kiunga Blue Eye.
