Can your tank handle Neolamprologus Pulcher and Platinum Hatchet?

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 Pulcher is a semi-aggressive species (7/10), while Platinum Hatchet is peaceful (1/10). This notable difference means Neolamprologus Pulcher may occasionally assert dominance over Platinum Hatchet.

Large aggression gap (6 points) between Neolamprologus Pulcher and Platinum Hatchet increases stress risk for the more peaceful fish.

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

Additional behavioural considerations to keep in mind: Aggressive fish may bully and stress shy, slow-moving species.

Worth noting: Platinum Hatchet 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 Pulcher (8–9) and Platinum Hatchet (5.5–7.5) do not overlap, making it impossible to satisfy both species simultaneously.

For general hardness, the shared comfort zone is 10–12 dGH. Regular testing will ensure conditions stay within this range.

Tank Setup

To house Neolamprologus Pulcher and Platinum Hatchet together, plan for an aquarium of at least 110 litres with a minimum length of 90 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), 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 Pulcher and Platinum Hatchet 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 Pulcher and Platinum Hatchet live together?

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

What size tank do Neolamprologus Pulcher and Platinum Hatchet need?

A minimum of 110 litres (tank length at least 90 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 Pulcher and Platinum Hatchet 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 Pulcher or Platinum Hatchet aggressive?

Neolamprologus Pulcher is semi-aggressive (7/10) and Platinum Hatchet is peaceful (1/10). The gap in aggression levels means the calmer fish may experience stress from the more assertive one.

What pH do Neolamprologus Pulcher and Platinum Hatchet need?

Their pH requirements do not overlap. Neolamprologus Pulcher prefers 8–9, while Platinum Hatchet needs 5.5–7.5. 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.
