Reviewed by Guidarium Editorial DeskUpdated May 7, 2026
Not Recommended

Amazon Puffer and Livingston's Cichlid 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.

Can your tank handle Amazon Puffer and Livingston's Cichlid?

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

Amazon Puffer is a generally mild-mannered species (3/10), while Livingston's Cichlid is semi-aggressive (8/10). This notable difference means Livingston's Cichlid may occasionally assert dominance over Amazon Puffer.

Amazon Puffer and Livingston's Cichlid 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 Livingston's Cichlid (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.

Tank Setup

To house Amazon Puffer and Livingston's Cichlid together, plan for an aquarium of at least 470 litres with a minimum length of 150 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), Driftwood (Digestion/Hiding), Plants - Densely covered, Shells (Breeding/Hiding). 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

Amazon Puffer and Livingston's Cichlid 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.

Suitable Tank Sizes

Standard aquarium sizes large enough for both Amazon Puffer and Livingston's Cichlid.

Frequently Asked Questions

Can Amazon Puffer and Livingston's Cichlid 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 Livingston's Cichlid need?

A minimum of 470 litres (tank length at least 150 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 Livingston's Cichlid 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 Livingston's Cichlid aggressive?

Amazon Puffer is generally mild-mannered (3/10) and Livingston's Cichlid is semi-aggressive (8/10). The gap in aggression levels means the calmer fish may experience stress from the more assertive one.

What pH do Amazon Puffer and Livingston's Cichlid need?

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

Will Amazon Puffer nip Livingston's Cichlid's fins?

Amazon Puffer is a known fin nipper. If Livingston's Cichlid 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 Livingston's Cichlid's territorial behaviour?

Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives Livingston's 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 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.
