Can African Butterfly Cichlid and Mono Sebae (Brackish) Live Together?
African Butterfly Cichlid and Mono Sebae (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 Mono Sebae (Brackish) is generally mild-mannered (4/10). This modest difference means Mono Sebae (Brackish) may occasionally assert dominance over African Butterfly Cichlid.
African Butterfly Cichlid and Mono Sebae (Brackish) 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.
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 7.5 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 12–15 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 Mono Sebae (Brackish) together, plan for an aquarium of at least 480 litres with a minimum length of 150 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.
Note a potential conflict in setup requirements: Mono Sebae (Brackish) is a plant destroyer, which conflicts with African Butterfly Cichlid's requirement for live plants. Compromise where possible or prioritise the more critical need.
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 Mono Sebae (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 Mono Sebae (Brackish) need?▾
A minimum of 480 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 African Butterfly Cichlid and Mono Sebae (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 Mono Sebae (Brackish) aggressive?▾
African Butterfly Cichlid is generally mild-mannered (3/10) and Mono Sebae (Brackish) is generally mild-mannered (4/10). Their similar temperaments generally lead to a peaceful coexistence.
What pH do African Butterfly Cichlid and Mono Sebae (Brackish) need?▾
Both species overlap in the 7.5–7.5 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.
