Can Neolamprologus Similis and Panda Tetra Live Together?

Reviewed by Guidarium Editorial DeskUpdated May 7, 2026
Not Recommended

Neolamprologus Similis and Panda Tetra 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 Neolamprologus Similis and Panda Tetra?

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

Neolamprologus Similis is a moderately assertive species (6/10), while Panda Tetra is generally mild-mannered (4/10). This modest difference means Neolamprologus Similis may occasionally assert dominance over Panda Tetra.

In terms of spatial distribution, Neolamprologus Similis prefers the Bottom (Substrate) zone, whereas Panda Tetra occupies the Top (Surface) and Middle (Open Water) zones. Because they use different levels of the water column, territorial disputes are less likely and the tank will appear more balanced.

Worth noting: Panda Tetra 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 Neolamprologus Similis (7.8–9) and Panda Tetra (5.5–7.5) 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 Neolamprologus Similis and Panda Tetra together, plan for an aquarium of at least 60 litres with a minimum length of 60 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), Shells (Breeding/Hiding), Plants - Densely covered, Plants - Floating. 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

Neolamprologus Similis and Panda Tetra 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 Neolamprologus Similis and Panda Tetra live together?

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

What size tank do Neolamprologus Similis and Panda Tetra need?

A minimum of 60 litres (tank length at least 60 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 Neolamprologus Similis and Panda Tetra 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 Neolamprologus Similis or Panda Tetra aggressive?

Neolamprologus Similis is moderately assertive (6/10) and Panda Tetra is generally mild-mannered (4/10). Their similar temperaments generally lead to a peaceful coexistence.

What pH do Neolamprologus Similis and Panda Tetra need?

Their pH requirements do not overlap. Neolamprologus Similis prefers 7.8–9, while Panda Tetra needs 5.5–7.5. This makes them incompatible in the same water chemistry.

Will Panda Tetra nip Neolamprologus Similis's fins?

Panda Tetra is a known fin nipper. If Neolamprologus Similis has long or flowing fins, there is a real risk of fin damage. Keeping Panda Tetra in a larger group can help redirect nipping behaviour toward conspecifics.

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.
