Can Agassiz's Dwarf Cichlid and Tanganyikan Clown Cichlid (Eretmodus) Live Together?
Agassiz's Dwarf Cichlid and Tanganyikan Clown Cichlid (Eretmodus) are not recommended as tank mates due to conflicting pH requirements and incompatible hardness ranges. Housing these species together is likely to result in stress, health problems, or direct harm to one or both fish.

Behaviour & Temperament
Agassiz's Dwarf Cichlid is a moderately assertive species (5/10), while Tanganyikan Clown Cichlid (Eretmodus) is semi-aggressive (7/10). This modest difference means Tanganyikan Clown Cichlid (Eretmodus) may occasionally assert dominance over Agassiz's Dwarf Cichlid.
Agassiz's Dwarf Cichlid 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.
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 Agassiz's Dwarf Cichlid (4.5–7) and Tanganyikan Clown Cichlid (Eretmodus) (8–9.5) do not overlap, making it impossible to satisfy both species simultaneously.
Hardness requirements are incompatible: Agassiz's Dwarf Cichlid needs 1–8 dGH while Tanganyikan Clown Cichlid (Eretmodus) requires 10–25 dGH.

Tank Setup
To house Agassiz's Dwarf Cichlid and Tanganyikan Clown Cichlid (Eretmodus) together, plan for an aquarium of at least 100 litres with a minimum length of 90 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), Leaf Litter/Blackwater, Driftwood (Digestion/Hiding), Plants - Densely covered, Smooth Gravel (Sensitive Barbels), Established Algae (Otocinclus). Meeting these requirements will help both species thrive.
Agassiz's Dwarf Cichlid prefers Low (Still Water) flow while Tanganyikan Clown Cichlid (Eretmodus) needs High (River/Stream) flow. Consider positioning filter outlets and using baffles to create zones of different current intensity within the same tank.

Frequently Asked Questions
Can Agassiz's Dwarf Cichlid 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 Agassiz's Dwarf Cichlid and Tanganyikan Clown Cichlid (Eretmodus) need?
A minimum of 100 litres (tank length at least 90 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 Agassiz's Dwarf Cichlid and Tanganyikan Clown Cichlid (Eretmodus) 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 Agassiz's Dwarf Cichlid or Tanganyikan Clown Cichlid (Eretmodus) aggressive?
Agassiz's Dwarf Cichlid is moderately assertive (5/10) and Tanganyikan Clown Cichlid (Eretmodus) is semi-aggressive (7/10). Their similar temperaments generally lead to a peaceful coexistence.
What pH do Agassiz's Dwarf Cichlid and Tanganyikan Clown Cichlid (Eretmodus) need?
Their pH requirements do not overlap. Agassiz's Dwarf Cichlid prefers 4.5–7, while Tanganyikan Clown Cichlid (Eretmodus) needs 8–9.5. This makes them incompatible in the same water chemistry.
How do I manage Agassiz's Dwarf Cichlid's territorial behaviour?
Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives Agassiz's Dwarf Cichlid 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.
