Behaviour & Temperament

Mbu Puffer is a semi-aggressive species (7/10), while Peacock Cichlid (Aulonocara) is moderately assertive (6/10). This modest difference means Mbu Puffer may occasionally assert dominance over Peacock Cichlid (Aulonocara).

Mbu Puffer and Peacock Cichlid (Aulonocara) 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.

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 Mbu Puffer and Peacock Cichlid (Aulonocara) to establish separate territories. Add plenty of line-of-sight breaks using driftwood, rocks, and dense planting to reduce territorial confrontations. Keep fin nippers in larger groups to distribute nipping behaviour among conspecifics rather than tank mates.

Water Parameters

The safe temperature window for both species falls between 24°C and 28°C. Aim for the midpoint of this range (around 26.0°C) for optimal comfort.

Both fish can tolerate a pH between 7.8 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 10–25 dGH. Regular testing will ensure conditions stay within this range. An aquarium test kit is recommended for monitoring.

Tank Setup

To house Mbu Puffer and Peacock Cichlid (Aulonocara) together, plan for an aquarium of at least 1800 litres with a minimum length of 240 cm. This accounts for the larger species' space requirements with an additional 20 % buffer to reduce territorial tension.

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), Shells (Breeding/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.

Frequently Asked Questions

Can Mbu Puffer and Peacock Cichlid (Aulonocara) live together?

They can coexist, but the pairing requires careful monitoring. Provide ample space (at least 1800 litres), plenty of hiding spots, and watch for signs of stress or aggression.

What size tank do Mbu Puffer and Peacock Cichlid (Aulonocara) need?

A minimum of 1800 litres (tank length at least 240 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 Mbu Puffer and Peacock Cichlid (Aulonocara) together?

Keep the aquarium between 24°C and 28°C. A target of around 26.0°C sits comfortably within both species' preferred ranges.

Are Mbu Puffer or Peacock Cichlid (Aulonocara) aggressive?

Mbu Puffer is semi-aggressive (7/10) and Peacock Cichlid (Aulonocara) is moderately assertive (6/10). Their similar temperaments generally lead to a peaceful coexistence.

What pH do Mbu Puffer and Peacock Cichlid (Aulonocara) need?

Both species overlap in the 7.8–8 pH range. Consistency is key — avoid sudden swings, and test regularly to stay within this window.

Will Mbu Puffer nip Peacock Cichlid (Aulonocara)'s fins?

Mbu Puffer is a known fin nipper. If Peacock Cichlid (Aulonocara) has long or flowing fins, there is a real risk of fin damage. Keeping Mbu Puffer in a larger group can help redirect nipping behaviour toward conspecifics.

How do I manage Peacock Cichlid (Aulonocara)'s territorial behaviour?

Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives Peacock Cichlid (Aulonocara) 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.
