Can your tank handle Duboisi Cichlid (Tropheus) and Motoro Stingray?

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

Duboisi Cichlid (Tropheus) is a semi-aggressive species (8/10), while Motoro Stingray is moderately assertive (5/10). This modest difference means Duboisi Cichlid (Tropheus) may occasionally assert dominance over Motoro Stingray.

Duboisi Cichlid (Tropheus) 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.

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 Duboisi Cichlid (Tropheus) (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.

Tank Setup

To house Duboisi Cichlid (Tropheus) and Motoro Stingray together, plan for an aquarium of at least 750 litres with a minimum length of 180 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), Established Algae (Otocinclus), 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.

Why This Pairing Usually Fails in Practice

Duboisi Cichlid (Tropheus) and Motoro Stingray 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 Duboisi Cichlid (Tropheus) and Motoro Stingray live together?

No. This combination is not recommended. Key incompatibilities — such as critical behavioural conflicts — make cohabitation unsafe.

What size tank do Duboisi Cichlid (Tropheus) and Motoro Stingray need?

A minimum of 750 litres (tank length at least 180 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 Duboisi Cichlid (Tropheus) and Motoro Stingray 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 Duboisi Cichlid (Tropheus) or Motoro Stingray aggressive?

Duboisi Cichlid (Tropheus) is semi-aggressive (8/10) and Motoro Stingray is moderately assertive (5/10). Their similar temperaments generally lead to a peaceful coexistence.

What pH do Duboisi Cichlid (Tropheus) and Motoro Stingray need?

Their pH requirements do not overlap. Duboisi Cichlid (Tropheus) prefers 8–9, while Motoro Stingray needs 6–7.5. This makes them incompatible in the same water chemistry.

How do I manage Duboisi Cichlid (Tropheus)'s territorial behaviour?

Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives Duboisi Cichlid (Tropheus) 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.
