Can Balloon Molly and Motoro Stingray Live Together?

Balloon Molly is a generally mild-mannered species (3/10), while Motoro Stingray is moderately assertive (5/10). This modest difference means Motoro Stingray may occasionally assert dominance over Balloon Molly.

In terms of spatial distribution, Balloon Molly prefers the Top (Surface) and Middle (Open Water) zones, whereas Motoro 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.

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

Hardness requirements are incompatible: Balloon Molly needs 12–25 dGH while Motoro Stingray requires 2–10 dGH.

To house Balloon Molly and Motoro Stingray 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: Established Algae (Otocinclus), Plants - Densely covered, Sand (Sifters), Smooth Gravel (Sensitive Barbels). Meeting these requirements will help both species thrive.

Balloon Molly prefers Low (Still Water) flow while Motoro Stingray needs High (River/Stream) flow. Consider positioning filter outlets and using baffles to create zones of different current intensity within the same tank.
