Can Dourada and Neolamprologus Fasciatus Live Together?

Reviewed by Guidarium Editorial DeskUpdated May 6, 2026
Not Recommended

Dourada and Neolamprologus Fasciatus 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.

Can your tank handle Dourada and Neolamprologus Fasciatus?

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

Both Dourada and Neolamprologus Fasciatus are moderately assertive species with an aggression score of 6/10. Their matching temperaments mean neither fish is likely to dominate the other in a shared aquarium.

Dourada and Neolamprologus Fasciatus both frequent the Middle (Open Water) and 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.

Worth noting: Dourada is a known jumper, so a tight-fitting lid is essential.

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 Dourada (6–7.5) and Neolamprologus Fasciatus (7.8–9) do not overlap, making it impossible to satisfy both species simultaneously.

For general hardness, the shared comfort zone is 10–15 dGH. Regular testing will ensure conditions stay within this range.

Tank Setup

To house Dourada and Neolamprologus Fasciatus together, plan for an aquarium of at least 15000 litres with a minimum length of 600 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

Dourada and Neolamprologus Fasciatus 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 Dourada and Neolamprologus Fasciatus live together?

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

What size tank do Dourada and Neolamprologus Fasciatus need?

A minimum of 15000 litres (tank length at least 600 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 Dourada and Neolamprologus Fasciatus 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 Dourada or Neolamprologus Fasciatus aggressive?

Dourada is moderately assertive (6/10) and Neolamprologus Fasciatus is moderately assertive (6/10). Their similar temperaments generally lead to a peaceful coexistence.

What pH do Dourada and Neolamprologus Fasciatus need?

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

How do I manage Neolamprologus Fasciatus's territorial behaviour?

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