Behaviour & Temperament
Agassiz's Dwarf Cichlid is a moderately assertive species (5/10), while Lake Tebera Rainbowfish is peaceful (2/10). This modest difference means Agassiz's Dwarf Cichlid may occasionally assert dominance over Lake Tebera Rainbowfish.
In terms of spatial distribution, Agassiz's Dwarf Cichlid prefers the Bottom (Substrate) zone, whereas Lake Tebera Rainbowfish occupies the Middle (Open Water) and Top (Surface) zones. Because they use different levels of the water column, territorial disputes are less likely and the tank will appear more balanced.
Additional behavioural considerations to keep in mind: Hyperactive swimmers can stress shy, slow-moving species through constant motion. Aggressive eaters may outcompete shy fish for food, leading to malnutrition.
Worth noting: Lake Tebera Rainbowfish 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 25°C. Aim for the midpoint of this range (around 24.5°C) for optimal comfort.
The pH requirements of Agassiz's Dwarf Cichlid (4.5–7) and Lake Tebera Rainbowfish (7.2–8) do not overlap, making it impossible to satisfy both species simultaneously.
For general hardness, the shared comfort zone is 8–8 dGH. Regular testing will ensure conditions stay within this range.

Tank Setup
To house Agassiz's Dwarf Cichlid and Lake Tebera Rainbowfish together, plan for an aquarium of at least 110 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. Meeting these requirements will help both species thrive.
Both species do well with low (still water) water movement, so a standard filtration setup rated for the tank volume should suffice.

Frequently Asked Questions
Can Agassiz's Dwarf Cichlid and Lake Tebera Rainbowfish 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 Lake Tebera Rainbowfish need?
A minimum of 110 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 Lake Tebera Rainbowfish together?
Keep the aquarium between 24°C and 25°C. A target of around 24.5°C sits comfortably within both species' preferred ranges.
Are Agassiz's Dwarf Cichlid or Lake Tebera Rainbowfish aggressive?
Agassiz's Dwarf Cichlid is moderately assertive (5/10) and Lake Tebera Rainbowfish is peaceful (2/10). Their similar temperaments generally lead to a peaceful coexistence.
What pH do Agassiz's Dwarf Cichlid and Lake Tebera Rainbowfish need?
Their pH requirements do not overlap. Agassiz's Dwarf Cichlid prefers 4.5–7, while Lake Tebera Rainbowfish needs 7.2–8. 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.
