Can Demasoni Cichlid (Mbuna) and Red-Tail Catfish Live Together?

🔴Not Recommended

Demasoni Cichlid (Mbuna) and Red-Tail Catfish 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

Demasoni Cichlid (Mbuna) is a highly aggressive species (9/10), while Red-Tail Catfish is semi-aggressive (7/10). This modest difference means Demasoni Cichlid (Mbuna) may occasionally assert dominance over Red-Tail Catfish.

Both Demasoni Cichlid (Mbuna) and Red-Tail Catfish are highly aggressive, increasing the risk of violent confrontations.

Demasoni Cichlid (Mbuna) and Red-Tail Catfish 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.

Worth noting: Red-Tail Catfish is nocturnal and will be most active after lights-out, naturally reducing daytime encounters.

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 Red-Tail Catfish (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 Demasoni Cichlid (Mbuna) and Red-Tail Catfish together, plan for an aquarium of at least 4560 litres with a minimum length of 300 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), Smooth Gravel (Sensitive Barbels), Driftwood (Digestion/Hiding). 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 Red-Tail Catfish 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 Red-Tail Catfish need?

A minimum of 4560 litres (tank length at least 300 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 Red-Tail Catfish 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 Red-Tail Catfish aggressive?

Demasoni Cichlid (Mbuna) is highly aggressive (9/10) and Red-Tail Catfish is semi-aggressive (7/10). Their similar temperaments generally lead to a peaceful coexistence.

What pH do Demasoni Cichlid (Mbuna) and Red-Tail Catfish need?

Their pH requirements do not overlap. Demasoni Cichlid (Mbuna) prefers 7.6–8.6, while Red-Tail Catfish needs 6–7.5. 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.

Does Red-Tail Catfish being nocturnal affect compatibility?

Red-Tail Catfish is most active after lights-out, which naturally reduces daytime encounters with its tank mate. This can actually be beneficial, as both fish get undisturbed time to feed and explore. Just ensure food reaches Red-Tail Catfish during evening hours.
