Can Antennae Stingray and Flowerhorn Cichlid Live Together?

Antennae Stingray is a moderately assertive species (5/10), while Flowerhorn Cichlid is highly aggressive (10/10). This notable difference means Flowerhorn Cichlid may occasionally assert dominance over Antennae Stingray.

Antennae Stingray and Flowerhorn Cichlid 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.

The safe temperature window for both species falls between 26°C and 28°C. Aim for the midpoint of this range (around 27.0°C) for optimal comfort.

The pH requirements of Antennae Stingray (6–7) and Flowerhorn Cichlid (7.4–8) do not overlap, making it impossible to satisfy both species simultaneously.

For general hardness, the shared comfort zone is 9–10 dGH. Regular testing will ensure conditions stay within this range.

To house Antennae Stingray and Flowerhorn Cichlid 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). 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.
