Can Brevis Shelldweller and Buffalo Head Cichlid Live Together?
Brevis Shelldweller and Buffalo Head Cichlid 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.
At a Glance
Can your tank handle Brevis Shelldweller and Buffalo Head Cichlid?
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
Brevis Shelldweller is a moderately assertive species (5/10), while Buffalo Head Cichlid is moderately assertive (6/10). This modest difference means Buffalo Head Cichlid may occasionally assert dominance over Brevis Shelldweller.
Brevis Shelldweller and Buffalo Head Cichlid 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.
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 Brevis Shelldweller (8–9) and Buffalo Head Cichlid (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 Brevis Shelldweller and Buffalo Head Cichlid together, plan for an aquarium of at least 110 litres with a minimum length of 80 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), Shells (Breeding/Hiding), 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.
Why This Pairing Usually Fails in Practice
Brevis Shelldweller and Buffalo Head Cichlid are the kind of pair that can look acceptable in a shop but become a maintenance problem at home. The main risk is not a single number in the chart; it is the way incompatible behavior, water needs, or pressure on space compounds over time once both fish are established in the same tank.

Frequently Asked Questions
Can Brevis Shelldweller and Buffalo Head Cichlid live together?
No. This combination is not recommended. Key incompatibilities — such as critical behavioural conflicts — make cohabitation unsafe.
What size tank do Brevis Shelldweller and Buffalo Head Cichlid need?
A minimum of 110 litres (tank length at least 80 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 Brevis Shelldweller and Buffalo Head Cichlid 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 Brevis Shelldweller or Buffalo Head Cichlid aggressive?
Brevis Shelldweller is moderately assertive (5/10) and Buffalo Head Cichlid is moderately assertive (6/10). Their similar temperaments generally lead to a peaceful coexistence.
What pH do Brevis Shelldweller and Buffalo Head Cichlid need?
Their pH requirements do not overlap. Brevis Shelldweller prefers 8–9, while Buffalo Head Cichlid needs 6–7.5. This makes them incompatible in the same water chemistry.
How do I manage Brevis Shelldweller's territorial behaviour?
Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives Brevis Shelldweller 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.
