Behaviour & Temperament
Antennae Stingray is a moderately assertive species (5/10), while Masked Julie (Julidochromis) is moderately assertive (6/10). This modest difference means Masked Julie (Julidochromis) may occasionally assert dominance over Antennae Stingray.
Antennae Stingray and Masked Julie (Julidochromis) 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.
Water Parameters
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 Antennae Stingray (6–7) and Masked Julie (Julidochromis) (8–9) 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.

Tank Setup
To house Antennae Stingray and Masked Julie (Julidochromis) 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.

Frequently Asked Questions
Can Antennae Stingray and Masked Julie (Julidochromis) live together?
No. This combination is not recommended. Key incompatibilities — such as critical behavioural conflicts — make cohabitation unsafe.
What size tank do Antennae Stingray and Masked Julie (Julidochromis) need?
A minimum of 2500 litres (tank length at least 240 cm) is recommended. This provides enough space for both species to establish their own areas and reduces the likelihood of territorial disputes.
What water temperature is best for Antennae Stingray and Masked Julie (Julidochromis) together?
Keep the aquarium between 24°C and 27°C. A target of around 25.5°C sits comfortably within both species' preferred ranges.
Are Antennae Stingray or Masked Julie (Julidochromis) aggressive?
Antennae Stingray is moderately assertive (5/10) and Masked Julie (Julidochromis) is moderately assertive (6/10). Their similar temperaments generally lead to a peaceful coexistence.
What pH do Antennae Stingray and Masked Julie (Julidochromis) need?
Their pH requirements do not overlap. Antennae Stingray prefers 6–7, while Masked Julie (Julidochromis) needs 8–9. This makes them incompatible in the same water chemistry.
How do I manage Masked Julie (Julidochromis)'s territorial behaviour?
Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives Masked Julie (Julidochromis) space to claim a territory without encroaching on the other fish's area. Adding décor that divides the tank into distinct zones works especially well.
