Can Motoro Stingray and Neolamprologus Similis Live Together?

Reviewed by Guidarium Editorial DeskUpdated May 6, 2026
Not Recommended

Motoro Stingray and Neolamprologus Similis are not recommended as tank mates due to conflicting pH requirements and piscivorous fish will prey on nano-sized tank mates.. Housing these species together is likely to result in stress, health problems, or direct harm to one or both fish.

Can your tank handle Motoro Stingray and Neolamprologus Similis?

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

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

Motoro Stingray and Neolamprologus Similis 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.

There is a critical concern: the Piscivore (Eats small/nano fish) behaviour of one fish directly conflicts with the Nano / Bite-sized (Predation Risk) trait of the other — piscivorous fish will prey on nano-sized tank mates..

Additional behavioural considerations to keep in mind: Shrimp eaters may also prey on very small nano fish.

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 Motoro Stingray (6–7.5) and Neolamprologus Similis (7.8–9) 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 Motoro Stingray and Neolamprologus Similis 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), Smooth Gravel (Sensitive Barbels), Shells (Breeding/Hiding). Meeting these requirements will help both species thrive.

Both species do well with high (river/stream) water movement, so a standard filtration setup rated for the tank volume should suffice.

Why This Pairing Usually Fails in Practice

Motoro Stingray and Neolamprologus Similis 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.

Diet & Feeding

Feeding time deserves special attention with this pairing. Motoro Stingray is a known shrimp eater and may prey on small invertebrates or nano fish like Neolamprologus Similis.

Frequently Asked Questions

Can Motoro Stingray and Neolamprologus Similis live together?

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

What size tank do Motoro Stingray and Neolamprologus Similis 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 Motoro Stingray and Neolamprologus Similis 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 Motoro Stingray or Neolamprologus Similis aggressive?

Motoro Stingray is moderately assertive (5/10) and Neolamprologus Similis is moderately assertive (6/10). Their similar temperaments generally lead to a peaceful coexistence.

What pH do Motoro Stingray and Neolamprologus Similis need?

Their pH requirements do not overlap. Motoro Stingray prefers 6–7.5, while Neolamprologus Similis needs 7.8–9. This makes them incompatible in the same water chemistry.

How do I manage Neolamprologus Similis's territorial behaviour?

Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives Neolamprologus Similis 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.
