Can Afra Cichlid and Plain Silver Dollar Live Together?

Not Recommended

Afra Cichlid and Plain Silver Dollar are not recommended as tank mates due to conflicting pH requirements. Housing these species together is likely to result in stress, health problems, or direct harm to one or both fish.

Can your tank handle Afra Cichlid and Plain Silver Dollar?

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 Plain Silver Dollar is peaceful (2/10). This notable difference means Afra Cichlid may occasionally assert dominance over Plain Silver Dollar.

Large aggression gap (6 points) between Afra Cichlid and Plain Silver Dollar increases stress risk for the more peaceful fish.

Afra Cichlid and Plain Silver Dollar 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.

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.

Worth noting: Plain Silver Dollar 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.

The pH requirements of Afra Cichlid (7.6–8.6) and Plain Silver Dollar (6–7.5) do not overlap, making it impossible to satisfy both species simultaneously.

For general hardness, the shared comfort zone is 10–15 dGH. Regular testing will ensure conditions stay within this range.

Tank Setup

To house Afra Cichlid and Plain Silver Dollar together, plan for an aquarium of at least 371 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), 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.

Suitable Tank Sizes

Standard aquarium sizes large enough for both Afra Cichlid and Plain Silver Dollar.

Frequently Asked Questions

Can Afra Cichlid and Plain Silver Dollar 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 Plain Silver Dollar need?

A minimum of 371 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 Plain Silver Dollar 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 Plain Silver Dollar aggressive?

Afra Cichlid is semi-aggressive (8/10) and Plain Silver Dollar 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 Plain Silver Dollar need?

Their pH requirements do not overlap. Afra Cichlid prefers 7.6–8.6, while Plain Silver Dollar needs 6–7.5. This makes them incompatible in the same water chemistry.

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.
