Behaviour & Temperament

Demasoni Cichlid (Mbuna) is a highly aggressive species (9/10), while Silver Dollar is peaceful (2/10). This notable difference means Demasoni Cichlid (Mbuna) may occasionally assert dominance over Silver Dollar.

Large aggression gap (7 points) between Demasoni Cichlid (Mbuna) and Silver Dollar increases stress risk for the more peaceful fish.

Demasoni Cichlid (Mbuna) and 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: 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 Demasoni Cichlid (Mbuna) (7.6–8.6) and Silver Dollar (5.5–7.5) 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. An aquarium test kit is recommended for monitoring.

Tank Setup

To house Demasoni Cichlid (Mbuna) and Silver Dollar together, plan for an aquarium of at least 336 litres with a minimum length of 120 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), Established Algae (Otocinclus), Driftwood (Digestion/Hiding), Smooth Gravel (Sensitive Barbels). Meeting these requirements will help both species thrive.

Both species do well with high (river/stream) water movement, so a standard filtration setup rated for the tank volume should suffice.

Frequently Asked Questions

Can Demasoni Cichlid (Mbuna) and Silver Dollar live together?

No. This combination is not recommended. Key incompatibilities — such as critical behavioural conflicts — make cohabitation unsafe.

What size tank do Demasoni Cichlid (Mbuna) and Silver Dollar need?

A minimum of 336 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 Demasoni Cichlid (Mbuna) and 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 Demasoni Cichlid (Mbuna) or Silver Dollar aggressive?

Demasoni Cichlid (Mbuna) is highly aggressive (9/10) and 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 Demasoni Cichlid (Mbuna) and Silver Dollar need?

Their pH requirements do not overlap. Demasoni Cichlid (Mbuna) prefers 7.6–8.6, while Silver Dollar needs 5.5–7.5. This makes them incompatible in the same water chemistry.

How do I manage Demasoni Cichlid (Mbuna)'s territorial behaviour?

Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives Demasoni Cichlid (Mbuna) 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.
