Can Teacup Stingray (Common Freshwater Ray) and Yellow Shrimp Live Together?

Teacup Stingray (Common Freshwater Ray) is a moderately assertive species (6/10), while Yellow Shrimp is peaceful (0/10). This notable difference means Teacup Stingray (Common Freshwater Ray) may occasionally assert dominance over Yellow Shrimp.

Large aggression gap (6 points) between Teacup Stingray (Common Freshwater Ray) and Yellow Shrimp increases stress risk for the more peaceful fish.

Teacup Stingray (Common Freshwater Ray) and Yellow Shrimp 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.

There is a critical concern: the Piscivore (Eats small/nano fish) behaviour of one fish directly conflicts with the Nano / Bite-sized (Predation Risk) 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.

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 6.5 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 6–12 dGH. Regular testing will ensure conditions stay within this range.

To house Teacup Stingray (Common Freshwater Ray) and Yellow Shrimp 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: Sand (Sifters), Smooth Gravel (Sensitive Barbels), Plants - Densely covered, Established Algae (Otocinclus), Leaf Litter/Blackwater. 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.

Teacup Stingray (Common Freshwater Ray) and Yellow Shrimp 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. Teacup Stingray (Common Freshwater Ray) is a known shrimp eater and may prey on small invertebrates or nano fish like Yellow Shrimp.
