Can Antennae Stingray and Pseudotropheus sp. Kingsizei Live Together?
Antennae Stingray and Pseudotropheus sp. Kingsizei are not recommended as tank mates due to conflicting pH requirements. Housing these species together is likely to result in stress, health problems, or direct harm to one or both fish.
At a Glance
Can your tank handle Antennae Stingray and Pseudotropheus sp. Kingsizei?
Compatibility is only part of the answer. Test both fish with your real tank size, current stock, and maintenance needs to see if you have enough space and a safe stocking level before you add them.
Behaviour & Temperament
Antennae Stingray is a moderately assertive species (5/10), while Pseudotropheus sp. Kingsizei is semi-aggressive (8/10). This modest difference means Pseudotropheus sp. Kingsizei may occasionally assert dominance over Antennae Stingray.
Antennae Stingray and Pseudotropheus sp. Kingsizei 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 28°C. Aim for the midpoint of this range (around 26.0°C) for optimal comfort.
The pH requirements of Antennae Stingray (6–7) and Pseudotropheus sp. Kingsizei (7.5–8.5) 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.
Tank Setup
To house Antennae Stingray and Pseudotropheus sp. Kingsizei 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). 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.
Why This Pairing Usually Fails in Practice
Antennae Stingray and Pseudotropheus sp. Kingsizei are the kind of pair that can look acceptable in a shop but become a maintenance problem at home. The main risk is not a single number in the chart; it is the way incompatible behavior, water needs, or pressure on space compounds over time once both fish are established in the same tank.
Frequently Asked Questions
Can Antennae Stingray and Pseudotropheus sp. Kingsizei 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 Pseudotropheus sp. Kingsizei 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 Pseudotropheus sp. Kingsizei together?
Keep the aquarium between 24°C and 28°C. A target of around 26.0°C sits comfortably within both species' preferred ranges.
Are Antennae Stingray or Pseudotropheus sp. Kingsizei aggressive?
Antennae Stingray is moderately assertive (5/10) and Pseudotropheus sp. Kingsizei is semi-aggressive (8/10). Their similar temperaments generally lead to a peaceful coexistence.
What pH do Antennae Stingray and Pseudotropheus sp. Kingsizei need?
Their pH requirements do not overlap. Antennae Stingray prefers 6–7, while Pseudotropheus sp. Kingsizei needs 7.5–8.5. This makes them incompatible in the same water chemistry.
How do I manage Pseudotropheus sp. Kingsizei's territorial behaviour?
Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives Pseudotropheus sp. Kingsizei 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.
