Can Abei Puffer and Dickfeld's Julie Live Together?
Abei Puffer and Dickfeld's Julie 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.
At a Glance
Can your tank handle Abei Puffer and Dickfeld's Julie?
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
Abei Puffer is a highly aggressive species (9/10), while Dickfeld's Julie is moderately assertive (6/10). This modest difference means Abei Puffer may occasionally assert dominance over Dickfeld's Julie.
Abei Puffer and Dickfeld's Julie 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.
Additional behavioural considerations to keep in mind: Two territorial species may clash over territory, especially in smaller tanks.
Water Parameters
The safe temperature window for both species falls between 24°C and 27°C. Aim for the midpoint of this range (around 25.5°C) for optimal comfort.
The pH requirements of Abei Puffer (6–7.8) and Dickfeld's Julie (8–9) 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 Abei Puffer and Dickfeld's Julie together, plan for an aquarium of at least 114 litres with a minimum length of 80 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. 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.

Frequently Asked Questions
Can Abei Puffer and Dickfeld's Julie live together?
No. This combination is not recommended. Key incompatibilities — such as critical behavioural conflicts — make cohabitation unsafe.
What size tank do Abei Puffer and Dickfeld's Julie need?
A minimum of 114 litres (tank length at least 80 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 Abei Puffer and Dickfeld's Julie together?
Keep the aquarium between 24°C and 27°C. A target of around 25.5°C sits comfortably within both species' preferred ranges.
Are Abei Puffer or Dickfeld's Julie aggressive?
Abei Puffer is highly aggressive (9/10) and Dickfeld's Julie is moderately assertive (6/10). Their similar temperaments generally lead to a peaceful coexistence.
What pH do Abei Puffer and Dickfeld's Julie need?
Their pH requirements do not overlap. Abei Puffer prefers 6–7.8, while Dickfeld's Julie needs 8–9. This makes them incompatible in the same water chemistry.
Will Abei Puffer nip Dickfeld's Julie's fins?
Abei Puffer is a known fin nipper. If Dickfeld's Julie has long or flowing fins, there is a real risk of fin damage. Keeping Abei Puffer in a larger group can help redirect nipping behaviour toward conspecifics.
How do I manage Abei Puffer's territorial behaviour?
Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives Abei Puffer 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.
