Can Amazon Puffer and Auratus Cichlid (Mbuna) Live Together?

🔴Not Recommended

Amazon Puffer and Auratus Cichlid (Mbuna) 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.

Behaviour & Temperament

Amazon Puffer is a generally mild-mannered species (3/10), while Auratus Cichlid (Mbuna) is highly aggressive (9/10). This notable difference means Auratus Cichlid (Mbuna) may occasionally assert dominance over Amazon Puffer.

Large aggression gap (6 points) between Amazon Puffer and Auratus Cichlid (Mbuna) increases stress risk for the more peaceful fish.

Amazon Puffer and Auratus Cichlid (Mbuna) 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.

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

Water Parameters

The safe temperature window for both species falls between 23°C and 28°C. Aim for the midpoint of this range (around 25.5°C) for optimal comfort.

The pH requirements of Amazon Puffer (5.5–7.5) and Auratus Cichlid (Mbuna) (7.6–8.6) 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. An aquarium test kit is recommended for monitoring.

Tank Setup

To house Amazon Puffer and Auratus Cichlid (Mbuna) together, plan for an aquarium of at least 240 litres with a minimum length of 120 cm. This accounts for the larger species' space requirements with an additional 20 % buffer to reduce territorial tension.

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), Driftwood (Digestion/Hiding), Plants - Densely covered, Shells (Breeding/Hiding), Established Algae (Otocinclus). Meeting these requirements will help both species thrive.

Note a potential conflict in setup requirements: Auratus Cichlid (Mbuna) is a plant destroyer, which conflicts with Amazon Puffer's requirement for live plants. Compromise where possible or prioritise the more critical need.

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 Amazon Puffer and Auratus Cichlid (Mbuna) live together?

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

What size tank do Amazon Puffer and Auratus Cichlid (Mbuna) need?

A minimum of 240 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 Amazon Puffer and Auratus Cichlid (Mbuna) together?

Keep the aquarium between 23°C and 28°C. A target of around 25.5°C sits comfortably within both species' preferred ranges.

Are Amazon Puffer or Auratus Cichlid (Mbuna) aggressive?

Amazon Puffer is generally mild-mannered (3/10) and Auratus Cichlid (Mbuna) is highly aggressive (9/10). The gap in aggression levels means the calmer fish may experience stress from the more assertive one.

What pH do Amazon Puffer and Auratus Cichlid (Mbuna) need?

Their pH requirements do not overlap. Amazon Puffer prefers 5.5–7.5, while Auratus Cichlid (Mbuna) needs 7.6–8.6. This makes them incompatible in the same water chemistry.

Will Amazon Puffer nip Auratus Cichlid (Mbuna)'s fins?

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

How do I manage Auratus Cichlid (Mbuna)'s territorial behaviour?

Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives Auratus Cichlid (Mbuna) 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 Amazon Puffer being nocturnal affect compatibility?

Amazon Puffer 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 Amazon Puffer during evening hours.
