Can Auratus Cichlid (Mbuna) and Serpae Tetra Live Together?

🔴Not Recommended

Auratus Cichlid (Mbuna) and Serpae Tetra 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 Serpae Tetra is moderately assertive (5/10). This notable difference means Auratus Cichlid (Mbuna) may occasionally assert dominance over Serpae Tetra.

Auratus Cichlid (Mbuna) and Serpae Tetra 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.

Water Parameters

The safe temperature window for both species falls between 23°C and 28°C. Aim for the midpoint of this range (around 25.5°C) for optimal comfort.

The pH requirements of Auratus Cichlid (Mbuna) (7.6–8.6) and Serpae Tetra (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 Auratus Cichlid (Mbuna) and Serpae Tetra together, plan for an aquarium of at least 240 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), Plants - Densely covered. Meeting these requirements will help both species thrive.

Note a potential conflict in setup requirements: Auratus Cichlid (Mbuna) is a plant destroyer, which conflicts with Serpae Tetra's requirement for live plants. Compromise where possible or prioritise the more critical need.

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 Serpae Tetra 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 Serpae Tetra need?

A minimum of 240 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 Serpae Tetra together?

Keep the aquarium between 23°C and 28°C. A target of around 25.5°C sits comfortably within both species' preferred ranges.

Are Auratus Cichlid (Mbuna) or Serpae Tetra aggressive?

Auratus Cichlid (Mbuna) is highly aggressive (9/10) and Serpae Tetra 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 Serpae Tetra need?

Their pH requirements do not overlap. Auratus Cichlid (Mbuna) prefers 7.6–8.6, while Serpae Tetra needs 5–7.5. This makes them incompatible in the same water chemistry.

Will Serpae Tetra nip Auratus Cichlid (Mbuna)'s fins?

Serpae Tetra is a known fin nipper. If Auratus Cichlid (Mbuna) has long or flowing fins, there is a real risk of fin damage. Keeping Serpae Tetra in a larger group can help redirect nipping behaviour toward conspecifics.

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.
