Can African Butterfly Cichlid and Banded Archerfish (Brackish) Live Together?
African Butterfly Cichlid and Banded Archerfish (Brackish) 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.
At a Glance
Behaviour & Temperament
African Butterfly Cichlid is a generally mild-mannered species (3/10), while Banded Archerfish (Brackish) is moderately assertive (6/10). This modest difference means Banded Archerfish (Brackish) may occasionally assert dominance over African Butterfly Cichlid.
In terms of spatial distribution, African Butterfly Cichlid prefers the Middle (Open Water) and Bottom (Substrate) zones, whereas Banded Archerfish (Brackish) occupies the Top (Surface) zone. 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 27°C. Aim for the midpoint of this range (around 25.5°C) for optimal comfort.
Both fish can tolerate a pH between 7 and 7.5. Maintaining a stable value within this band is more important than hitting an exact number.
For general hardness, the shared comfort zone is 15–15 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 African Butterfly Cichlid and Banded Archerfish (Brackish) together, plan for an aquarium of at least 360 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), Smooth Gravel (Sensitive Barbels), Plants - Densely covered, Driftwood (Digestion/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.
Frequently Asked Questions
Can African Butterfly Cichlid and Banded Archerfish (Brackish) live together?▾
No. This combination is not recommended. Key incompatibilities — such as different water type needs — make cohabitation unsafe.
What size tank do African Butterfly Cichlid and Banded Archerfish (Brackish) need?▾
A minimum of 360 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 African Butterfly Cichlid and Banded Archerfish (Brackish) 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 African Butterfly Cichlid or Banded Archerfish (Brackish) aggressive?▾
African Butterfly Cichlid is generally mild-mannered (3/10) and Banded Archerfish (Brackish) is moderately assertive (6/10). Their similar temperaments generally lead to a peaceful coexistence.
What pH do African Butterfly Cichlid and Banded Archerfish (Brackish) need?▾
Both species overlap in the 7–7.5 pH range. Consistency is key — avoid sudden swings, and test regularly to stay within this window.
How do I manage African Butterfly Cichlid's territorial behaviour?▾
Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives African Butterfly 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.
