Can Antennae Stingray and Balloon Molly Live Together?

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

In terms of spatial distribution, Antennae Stingray prefers the Bottom (Substrate) zone, whereas Balloon Molly occupies the Top (Surface) and Middle (Open Water) zones. 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. Maintaining a stable value within this band is more important than hitting an exact number.

Hardness requirements are incompatible: Antennae Stingray needs 1–10 dGH while Balloon Molly requires 12–25 dGH.

To house Antennae Stingray and Balloon Molly together, plan for an aquarium of at least 2500 litres with a minimum length of 240 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), Established Algae (Otocinclus), Plants - Densely covered. 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.
