Can your tank handle Delhezi Bichir (Armored Bichir) 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

Delhezi Bichir (Armored Bichir) is a moderately assertive species (6/10), while Neolamprologus Pulcher is semi-aggressive (7/10). This modest difference means Neolamprologus Pulcher may occasionally assert dominance over Delhezi Bichir (Armored Bichir).

Delhezi Bichir (Armored Bichir) and Neolamprologus Pulcher 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.

Worth noting: Delhezi Bichir (Armored Bichir) is nocturnal and will be most active after lights-out, naturally reducing daytime encounters. Also, Delhezi Bichir (Armored Bichir) is a known jumper, so a tight-fitting lid is essential.

To improve the chances of a peaceful coexistence in this community tank: Provide a significantly larger tank (at least 50% more volume than the minimum) to allow both Delhezi Bichir (Armored Bichir) and Neolamprologus Pulcher to establish separate territories. Add plenty of line-of-sight breaks using driftwood, rocks, and dense planting to reduce territorial confrontations.

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.

Both fish can tolerate a pH between 8 and 8. Maintaining a stable value within this band is more important than hitting an exact number.

For general hardness, the shared comfort zone is 10–20 dGH. Regular testing will ensure conditions stay within this range.

Tank Setup

To house Delhezi Bichir (Armored Bichir) and Neolamprologus Pulcher together, plan for an aquarium of at least 280 litres with a minimum length of 120 cm. This recommendation combines the stricter species minimums with a community-load allowance so the pairing has realistic long-term space and filtration headroom.

Because this pairing requires extra vigilance, include plenty of hiding spots — caves, driftwood, and dense plant clusters — so the less dominant fish can retreat when needed.

Specific environmental needs for this combination include: Sand (Sifters), Smooth Gravel (Sensitive Barbels), Driftwood (Digestion/Hiding). 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 Needs Extra Planning in Practice

This pairing usually fails when the tank is treated like a standard mixed community and the caution flags are ignored. Delhezi Bichir (Armored Bichir) and Neolamprologus Pulcher need extra room, more cover, and closer observation during the first few weeks so small aggression, feeding, or territory issues do not snowball into a long-term problem.

What water temperature is best for Delhezi Bichir (Armored Bichir) 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 Delhezi Bichir (Armored Bichir) or Neolamprologus Pulcher aggressive?

Delhezi Bichir (Armored Bichir) is moderately assertive (6/10) and Neolamprologus Pulcher is semi-aggressive (7/10). Their similar temperaments generally lead to a peaceful coexistence.

What pH do Delhezi Bichir (Armored Bichir) and Neolamprologus Pulcher need?

Both species overlap in the 8–8 pH range. Consistency is key — avoid sudden swings, and test regularly to stay within this window.

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.

Does Delhezi Bichir (Armored Bichir) being nocturnal affect compatibility?

Delhezi Bichir (Armored Bichir) is most active after lights-out, which naturally reduces daytime encounters with its tank mate. This can actually be beneficial, as both fish get undisturbed time to feed and explore. Just ensure food reaches Delhezi Bichir (Armored Bichir) during evening hours.
