Can African Butterfly Cichlid and Ceylon Puffer (Brackish) Live Together?
African Butterfly Cichlid and Ceylon Puffer (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
Can your tank handle African Butterfly Cichlid and Ceylon Puffer (Brackish)?
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
African Butterfly Cichlid is a generally mild-mannered species (3/10), while Ceylon Puffer (Brackish) is semi-aggressive (8/10). This notable difference means Ceylon Puffer (Brackish) may occasionally assert dominance over African Butterfly Cichlid.
African Butterfly Cichlid and Ceylon Puffer (Brackish) 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.
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 Ceylon Puffer (Brackish) together, plan for an aquarium of at least 150 litres with a minimum length of 90 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), Smooth Gravel (Sensitive Barbels), Plants - Densely covered, Driftwood (Digestion/Hiding), Shells (Breeding/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 Ceylon Puffer (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 Ceylon Puffer (Brackish) need?
A minimum of 150 litres (tank length at least 90 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 Ceylon Puffer (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 Ceylon Puffer (Brackish) aggressive?
African Butterfly Cichlid is generally mild-mannered (3/10) and Ceylon Puffer (Brackish) is semi-aggressive (8/10). The gap in aggression levels means the calmer fish may experience stress from the more assertive one.
What pH do African Butterfly Cichlid and Ceylon Puffer (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.
Will Ceylon Puffer (Brackish) nip African Butterfly Cichlid's fins?
Ceylon Puffer (Brackish) is a known fin nipper. If African Butterfly Cichlid has long or flowing fins, there is a real risk of fin damage. Keeping Ceylon Puffer (Brackish) in a larger group can help redirect nipping behaviour toward conspecifics.
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.
