Can Amazon Leaf Fish and Mbu Puffer Live Together?
Amazon Leaf Fish and Mbu Puffer are not recommended as tank mates due to conflicting pH requirements and incompatible hardness ranges. Housing these species together is likely to result in stress, health problems, or direct harm to one or both fish.
At a Glance
Behaviour & Temperament
Amazon Leaf Fish is a peaceful species (2/10), while Mbu Puffer is semi-aggressive (7/10). This notable difference means Mbu Puffer may occasionally assert dominance over Amazon Leaf Fish.
Amazon Leaf Fish and Mbu Puffer both frequent the Middle (Open Water) region of the setup. This overlap can increase competition for space, so providing ample room and cover is important to keep both species comfortable.
Additional behavioural considerations to keep in mind: Aggressive fish may bully and stress shy, slow-moving species. Aggressive eaters may outcompete shy fish for food, leading to malnutrition.
Worth noting: Amazon Leaf Fish is nocturnal and will be most active after lights-out, naturally reducing daytime encounters.
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.
The pH requirements of Amazon Leaf Fish (5–6.8) and Mbu Puffer (7–8) do not overlap, making it impossible to satisfy both species simultaneously.
Hardness requirements are incompatible: Amazon Leaf Fish needs 0–8 dGH while Mbu Puffer requires 10–25 dGH.
Tank Setup
To house Amazon Leaf Fish and Mbu Puffer 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.
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: Leaf Litter/Blackwater, Plants - Densely covered, Driftwood (Digestion/Hiding), Plants - Floating, Sand (Sifters), Shells (Breeding/Hiding), Smooth Gravel (Sensitive Barbels). 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.
Diet & Feeding
Feeding time deserves special attention with this pairing. Mbu Puffer is an aggressive eater that may prevent Amazon Leaf Fish from getting enough food.
Because Mbu Puffer is a fast, competitive feeder, consider using sinking pellets or feeding at opposite ends of the setup to ensure Amazon Leaf Fish receives an adequate share.
Frequently Asked Questions
Can Amazon Leaf Fish and Mbu Puffer live together?▾
No. This combination is not recommended. Key incompatibilities — such as critical behavioural conflicts — make cohabitation unsafe.
What size tank do Amazon Leaf Fish and Mbu Puffer 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 Amazon Leaf Fish and Mbu Puffer 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 Amazon Leaf Fish or Mbu Puffer aggressive?▾
Amazon Leaf Fish is peaceful (2/10) and Mbu Puffer is semi-aggressive (7/10). The gap in aggression levels means the calmer fish may experience stress from the more assertive one.
What pH do Amazon Leaf Fish and Mbu Puffer need?▾
Their pH requirements do not overlap. Amazon Leaf Fish prefers 5–6.8, while Mbu Puffer needs 7–8. This makes them incompatible in the same water chemistry.
Will Mbu Puffer nip Amazon Leaf Fish's fins?▾
Mbu Puffer is a known fin nipper. If Amazon Leaf Fish 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.
Does Amazon Leaf Fish being nocturnal affect compatibility?▾
Amazon Leaf Fish 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 Leaf Fish during evening hours.
