Can Afra Cichlid and Blue Back Blue Eye Live Together?
Afra Cichlid and Blue Back Blue Eye 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 Afra Cichlid and Blue Back Blue Eye?
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
Afra Cichlid is a semi-aggressive species (8/10), while Blue Back Blue Eye is peaceful (2/10). This notable difference means Afra Cichlid may occasionally assert dominance over Blue Back Blue Eye.
Large aggression gap (6 points) between Afra Cichlid and Blue Back Blue Eye increases stress risk for the more peaceful fish.
Afra Cichlid and Blue Back Blue Eye 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.
Worth noting: Blue Back Blue Eye 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 7.6 and 8.5. Maintaining a stable value within this band is more important than hitting an exact number.
For general hardness, the shared comfort zone is 10–25 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 Afra Cichlid and Blue Back Blue Eye together, plan for an aquarium of at least 247 litres with a minimum length of 120 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), Established Algae (Otocinclus), 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 Afra Cichlid and Blue Back Blue Eye live together?
No. This combination is not recommended. Key incompatibilities — such as different water type needs — make cohabitation unsafe.
What size tank do Afra Cichlid and Blue Back Blue Eye need?
A minimum of 247 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 Afra Cichlid and Blue Back Blue Eye 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 Afra Cichlid or Blue Back Blue Eye aggressive?
Afra Cichlid is semi-aggressive (8/10) and Blue Back Blue Eye is peaceful (2/10). The gap in aggression levels means the calmer fish may experience stress from the more assertive one.
What pH do Afra Cichlid and Blue Back Blue Eye need?
Both species overlap in the 7.6–8.5 pH range. Consistency is key — avoid sudden swings, and test regularly to stay within this window.
How do I manage Afra Cichlid's territorial behaviour?
Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives Afra 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.
