Can Agassiz's Dwarf Cichlid and Neon Blue Cichlid Live Together?

Agassiz's Dwarf Cichlid is a moderately assertive species (5/10), while Neon Blue Cichlid is generally mild-mannered (3/10). This modest difference means Agassiz's Dwarf Cichlid may occasionally assert dominance over Neon Blue Cichlid.

Agassiz's Dwarf Cichlid and Neon Blue 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: Hyperactive swimmers can stress shy, slow-moving species through constant motion.

The safe temperature window for both species falls between 24°C and 27°C. Aim for the midpoint of this range (around 25.5°C) for optimal comfort.

The pH requirements of Agassiz's Dwarf Cichlid (4.5–7) and Neon Blue Cichlid (8–9) do not overlap, making it impossible to satisfy both species simultaneously.

Hardness requirements are incompatible: Agassiz's Dwarf Cichlid needs 1–8 dGH while Neon Blue Cichlid requires 10–20 dGH.

To house Agassiz's Dwarf Cichlid and Neon Blue Cichlid together, plan for an aquarium of at least 150 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). 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.
