Can Auratus Cichlid (Mbuna) and Severum Live Together?

🔴Not Recommended

Auratus Cichlid (Mbuna) and Severum 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.

Behaviour & Temperament

Auratus Cichlid (Mbuna) is a highly aggressive species (9/10), while Severum is moderately assertive (5/10). This notable difference means Auratus Cichlid (Mbuna) may occasionally assert dominance over Severum.

Auratus Cichlid (Mbuna) and Severum 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.

Additional behavioural considerations to keep in mind: Two territorial species may clash over territory, especially in smaller tanks.

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 Auratus Cichlid (Mbuna) (7.6–8.6) and Severum (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. An aquarium test kit is recommended for monitoring.

Tank Setup

To house Auratus Cichlid (Mbuna) and Severum 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 moderate (standard) water movement, so a standard filtration setup rated for the tank volume should suffice.

Frequently Asked Questions

Can Auratus Cichlid (Mbuna) and Severum live together?

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

What size tank do Auratus Cichlid (Mbuna) and Severum 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 Auratus Cichlid (Mbuna) and Severum 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 Auratus Cichlid (Mbuna) or Severum aggressive?

Auratus Cichlid (Mbuna) is highly aggressive (9/10) and Severum is moderately assertive (5/10). The gap in aggression levels means the calmer fish may experience stress from the more assertive one.

What pH do Auratus Cichlid (Mbuna) and Severum need?

Their pH requirements do not overlap. Auratus Cichlid (Mbuna) prefers 7.6–8.6, while Severum needs 6–7.5. This makes them incompatible in the same water chemistry.

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

Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives Auratus 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.
