Can Aequidens sp. Atabapo and Neon Blue Cichlid Live Together?
Aequidens sp. Atabapo and Neon Blue Cichlid 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.
At a Glance
Can your tank handle Aequidens sp. Atabapo and Neon Blue 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
Aequidens sp. Atabapo is a moderately assertive species (6/10), while Neon Blue Cichlid is generally mild-mannered (3/10). This modest difference means Aequidens sp. Atabapo may occasionally assert dominance over Neon Blue Cichlid.
Aequidens sp. Atabapo and Neon Blue Cichlid both frequent the Middle (Open Water) and 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.
Water Parameters
The safe temperature window for both species falls between 25°C and 27°C. Aim for the midpoint of this range (around 26.0°C) for optimal comfort.
The pH requirements of Aequidens sp. Atabapo (4.5–7) and Neon Blue Cichlid (8–9) do not overlap, making it impossible to satisfy both species simultaneously.
Hardness requirements are incompatible: Aequidens sp. Atabapo needs 1–8 dGH while Neon Blue Cichlid requires 10–20 dGH.

Tank Setup
To house Aequidens sp. Atabapo 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), Driftwood (Digestion/Hiding), Leaf Litter/Blackwater, 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.

Frequently Asked Questions
Can Aequidens sp. Atabapo and Neon Blue Cichlid live together?
No. This combination is not recommended. Key incompatibilities — such as critical behavioural conflicts — make cohabitation unsafe.
What size tank do Aequidens sp. Atabapo and Neon Blue Cichlid need?
A minimum of 150 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 Aequidens sp. Atabapo and Neon Blue Cichlid together?
Keep the aquarium between 25°C and 27°C. A target of around 26.0°C sits comfortably within both species' preferred ranges.
Are Aequidens sp. Atabapo or Neon Blue Cichlid aggressive?
Aequidens sp. Atabapo is moderately assertive (6/10) and Neon Blue Cichlid is generally mild-mannered (3/10). Their similar temperaments generally lead to a peaceful coexistence.
What pH do Aequidens sp. Atabapo and Neon Blue Cichlid need?
Their pH requirements do not overlap. Aequidens sp. Atabapo prefers 4.5–7, while Neon Blue Cichlid needs 8–9. This makes them incompatible in the same water chemistry.
How do I manage Aequidens sp. Atabapo's territorial behaviour?
Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives Aequidens sp. Atabapo 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.
