Behaviour & Temperament

Banded Cichlid is a generally mild-mannered species (4/10), while Delhezi Bichir (Armored Bichir) is moderately assertive (6/10). This modest difference means Delhezi Bichir (Armored Bichir) may occasionally assert dominance over Banded Cichlid.

Banded Cichlid and Delhezi Bichir (Armored Bichir) 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 Banded Cichlid and Delhezi Bichir (Armored Bichir) 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 29°C. Aim for the midpoint of this range (around 26.5°C) for optimal comfort.

Both fish can tolerate a pH between 6 and 7.2. Maintaining a stable value within this band is more important than hitting an exact number.

For general hardness, the shared comfort zone is 5–10 dGH. Regular testing will ensure conditions stay within this range.

Tank Setup

To house Banded Cichlid and Delhezi Bichir (Armored Bichir) 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), Driftwood (Digestion/Hiding), Smooth Gravel (Sensitive Barbels). 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 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. Banded Cichlid and Delhezi Bichir (Armored Bichir) 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 size tank do Banded Cichlid and Delhezi Bichir (Armored Bichir) need?

A minimum of 280 litres (tank length at least 120 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 Banded Cichlid and Delhezi Bichir (Armored Bichir) together?

Keep the aquarium between 24°C and 29°C. A target of around 26.5°C sits comfortably within both species' preferred ranges.

Are Banded Cichlid or Delhezi Bichir (Armored Bichir) aggressive?

Banded Cichlid is generally mild-mannered (4/10) and Delhezi Bichir (Armored Bichir) is moderately assertive (6/10). Their similar temperaments generally lead to a peaceful coexistence.

What pH do Banded Cichlid and Delhezi Bichir (Armored Bichir) need?

Both species overlap in the 6–7.2 pH range. Consistency is key — avoid sudden swings, and test regularly to stay within this window.

How do I manage Banded Cichlid's territorial behaviour?

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