Can Masked Julie (Julidochromis) and Motoro Stingray Live Together?

Masked Julie (Julidochromis) is a moderately assertive species (6/10), while Motoro Stingray is moderately assertive (5/10). This modest difference means Masked Julie (Julidochromis) may occasionally assert dominance over Motoro Stingray.

Masked Julie (Julidochromis) and Motoro Stingray 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 24°C and 27°C. Aim for the midpoint of this range (around 25.5°C) for optimal comfort.

The pH requirements of Masked Julie (Julidochromis) (8–9) and Motoro Stingray (6–7.5) do not overlap, making it impossible to satisfy both species simultaneously.

For general hardness, the shared comfort zone is 10–10 dGH. Regular testing will ensure conditions stay within this range. An aquarium test kit is recommended for monitoring.

To house Masked Julie (Julidochromis) and Motoro Stingray together, plan for an aquarium of at least 900 litres with a minimum length of 180 cm. This accounts for the larger species' space requirements with an additional 20 % buffer to reduce territorial tension.

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.
