Can your tank handle Sixbar Distichodus and Tanganyikan Clown Cichlid (Eretmodus)?

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

Both Sixbar Distichodus and Tanganyikan Clown Cichlid (Eretmodus) are semi-aggressive species with an aggression score of 7/10. Their matching temperaments mean neither fish is likely to dominate the other in a shared aquarium.

Both Sixbar Distichodus and Tanganyikan Clown Cichlid (Eretmodus) are highly aggressive, increasing the risk of violent confrontations.

Sixbar Distichodus and Tanganyikan Clown Cichlid (Eretmodus) 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: Sixbar Distichodus 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 26°C. Aim for the midpoint of this range (around 25.0°C) for optimal comfort.

The pH requirements of Sixbar Distichodus (6–7.5) and Tanganyikan Clown Cichlid (Eretmodus) (8–9.5) do not overlap, making it impossible to satisfy both species simultaneously.

For general hardness, the shared comfort zone is 10–20 dGH. Regular testing will ensure conditions stay within this range.

Tank Setup

To house Sixbar Distichodus and Tanganyikan Clown Cichlid (Eretmodus) together, plan for an aquarium of at least 1000 litres with a minimum length of 200 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), Smooth Gravel (Sensitive Barbels), Driftwood (Digestion/Hiding), Established Algae (Otocinclus). 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

Sixbar Distichodus and Tanganyikan Clown Cichlid (Eretmodus) 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 Sixbar Distichodus and Tanganyikan Clown Cichlid (Eretmodus) live together?

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

What size tank do Sixbar Distichodus and Tanganyikan Clown Cichlid (Eretmodus) need?

A minimum of 1000 litres (tank length at least 200 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 Sixbar Distichodus and Tanganyikan Clown Cichlid (Eretmodus) together?

Keep the aquarium between 24°C and 26°C. A target of around 25.0°C sits comfortably within both species' preferred ranges.

Are Sixbar Distichodus or Tanganyikan Clown Cichlid (Eretmodus) aggressive?

Sixbar Distichodus is semi-aggressive (7/10) and Tanganyikan Clown Cichlid (Eretmodus) is semi-aggressive (7/10). Their similar temperaments generally lead to a peaceful coexistence.

What pH do Sixbar Distichodus and Tanganyikan Clown Cichlid (Eretmodus) need?

Their pH requirements do not overlap. Sixbar Distichodus prefers 6–7.5, while Tanganyikan Clown Cichlid (Eretmodus) needs 8–9.5. This makes them incompatible in the same water chemistry.

Will Sixbar Distichodus nip Tanganyikan Clown Cichlid (Eretmodus)'s fins?

Sixbar Distichodus is a known fin nipper. If Tanganyikan Clown Cichlid (Eretmodus) has long or flowing fins, there is a real risk of fin damage. Keeping Sixbar Distichodus in a larger group can help redirect nipping behaviour toward conspecifics.

How do I manage Tanganyikan Clown Cichlid (Eretmodus)'s territorial behaviour?

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