Can Banded Archerfish (Brackish) and Mbu Puffer Live Together?

🔴Not Recommended

Banded Archerfish (Brackish) and Mbu Puffer are not recommended as tank mates due to incompatible water types. Housing these species together is likely to result in stress, health problems, or direct harm to one or both fish.

Behaviour & Temperament

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

In terms of spatial distribution, Banded Archerfish (Brackish) prefers the Top (Surface) zone, whereas Mbu Puffer occupies the Middle (Open Water) and Bottom (Substrate) zones. Because they use different levels of the water column, territorial disputes are less likely and the tank will appear more balanced.

Worth noting: Banded Archerfish (Brackish) is a known jumper, so a tight-fitting lid is essential.

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 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 15–25 dGH. Regular testing will ensure conditions stay within this range.

Crucially, these species require different water types — one needs freshwater while the other requires brackish conditions. This is a hard barrier to keeping them together.

Tank Setup

To house Banded Archerfish (Brackish) 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: Sand (Sifters), Driftwood (Digestion/Hiding), 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 Banded Archerfish (Brackish) and Mbu Puffer live together?

No. This combination is not recommended. Key incompatibilities — such as different water type needs — make cohabitation unsafe.

What size tank do Banded Archerfish (Brackish) 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 Banded Archerfish (Brackish) 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 Banded Archerfish (Brackish) or Mbu Puffer aggressive?

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

What pH do Banded Archerfish (Brackish) and Mbu Puffer need?

Both species overlap in the 7–8 pH range. Consistency is key — avoid sudden swings, and test regularly to stay within this window.

Will Mbu Puffer nip Banded Archerfish (Brackish)'s fins?

Mbu Puffer is a known fin nipper. If Banded Archerfish (Brackish) 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.
