Reviewed by Guidarium Editorial DeskUpdated May 6, 2026
Not Recommended

Cherry Barb and Neolamprologus Pulcher 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 Cherry Barb and Neolamprologus Pulcher?

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

Cherry Barb is a peaceful species (2/10), while Neolamprologus Pulcher is semi-aggressive (7/10). This notable difference means Neolamprologus Pulcher may occasionally assert dominance over Cherry Barb.

Cherry Barb and Neolamprologus Pulcher 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.

Additional behavioural considerations to keep in mind: Aggressive fish may bully and stress shy, slow-moving species. 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 Cherry Barb (6–7.5) and Neolamprologus Pulcher (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 Cherry Barb and Neolamprologus Pulcher together, plan for an aquarium of at least 75 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: Plants - Densely covered, Leaf Litter/Blackwater, Sand (Sifters). Meeting these requirements will help both species thrive.

Both species do well with low (still water) water movement, so a standard filtration setup rated for the tank volume should suffice.

Why This Pairing Usually Fails in Practice

Cherry Barb and Neolamprologus Pulcher 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. Neolamprologus Pulcher is a known shrimp eater and may prey on small invertebrates or nano fish like Cherry Barb.

Frequently Asked Questions

Can Cherry Barb and Neolamprologus Pulcher live together?

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

What size tank do Cherry Barb and Neolamprologus Pulcher need?

A minimum of 75 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 Cherry Barb and Neolamprologus Pulcher 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 Cherry Barb or Neolamprologus Pulcher aggressive?

Cherry Barb is peaceful (2/10) and Neolamprologus Pulcher is semi-aggressive (7/10). The gap in aggression levels means the calmer fish may experience stress from the more assertive one.

What pH do Cherry Barb and Neolamprologus Pulcher need?

Their pH requirements do not overlap. Cherry Barb prefers 6–7.5, while Neolamprologus Pulcher needs 8–9. This makes them incompatible in the same water chemistry.

How do I manage Neolamprologus Pulcher's territorial behaviour?

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