Can Afra Cichlid and Cardinal Shrimp (Sulawesi) Live Together?
Afra Cichlid and Cardinal Shrimp (Sulawesi) are not recommended as tank mates due to incompatible hardness ranges. 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 Cardinal Shrimp (Sulawesi)?
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 Cardinal Shrimp (Sulawesi) is peaceful (0/10). This notable difference means Afra Cichlid may occasionally assert dominance over Cardinal Shrimp (Sulawesi).
Large aggression gap (8 points) between Afra Cichlid and Cardinal Shrimp (Sulawesi) increases stress risk for the more peaceful fish.
Afra Cichlid and Cardinal Shrimp (Sulawesi) both frequent the 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.
Additional behavioural considerations to keep in mind: Aggressive fish may bully and stress shy, slow-moving species. Hyperactive swimmers can stress shy, slow-moving species through constant motion.
Water Parameters
The safe temperature window for both species falls between 26°C and 28°C. Aim for the midpoint of this range (around 27.0°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.
Hardness requirements are incompatible: Afra Cichlid needs 10–25 dGH while Cardinal Shrimp (Sulawesi) requires 4–8 dGH.

Tank Setup
To house Afra Cichlid and Cardinal Shrimp (Sulawesi) 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), 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 Afra Cichlid and Cardinal Shrimp (Sulawesi) live together?
No. This combination is not recommended. Key incompatibilities — such as critical behavioural conflicts — make cohabitation unsafe.
What size tank do Afra Cichlid and Cardinal Shrimp (Sulawesi) 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 Cardinal Shrimp (Sulawesi) together?
Keep the aquarium between 26°C and 28°C. A target of around 27.0°C sits comfortably within both species' preferred ranges.
Are Afra Cichlid or Cardinal Shrimp (Sulawesi) aggressive?
Afra Cichlid is semi-aggressive (8/10) and Cardinal Shrimp (Sulawesi) is peaceful (0/10). The gap in aggression levels means the calmer fish may experience stress from the more assertive one.
What pH do Afra Cichlid and Cardinal Shrimp (Sulawesi) 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.
