Can Afra Cichlid and Neon Green Rasbora (Kubotai) Live Together?

Not Recommended

Afra Cichlid and Neon Green Rasbora (Kubotai) are not recommended as tank mates due to conflicting pH requirements. Housing these species together is likely to result in stress, health problems, or direct harm to one or both fish.

Can your tank handle Afra Cichlid and Neon Green Rasbora (Kubotai)?

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

Afra Cichlid is a semi-aggressive species (8/10), while Neon Green Rasbora (Kubotai) is peaceful (1/10). This notable difference means Afra Cichlid may occasionally assert dominance over Neon Green Rasbora (Kubotai).

Large aggression gap (7 points) between Afra Cichlid and Neon Green Rasbora (Kubotai) increases stress risk for the more peaceful fish.

Afra Cichlid and Neon Green Rasbora (Kubotai) both frequent the Middle (Open Water) 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: Neon Green Rasbora (Kubotai) is a known jumper, so a tight-fitting lid is essential.

Water Parameters

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

The pH requirements of Afra Cichlid (7.6–8.6) and Neon Green Rasbora (Kubotai) (6–7.5) do not overlap, making it impossible to satisfy both species simultaneously.

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

Tank Setup

To house Afra Cichlid and Neon Green Rasbora (Kubotai) together, plan for an aquarium of at least 247 litres with a minimum length of 120 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), Established Algae (Otocinclus), Plants - Densely covered, Plants - lighly covered, Leaf Litter/Blackwater. Meeting these requirements will help both species thrive.

Note a potential conflict in setup requirements: Afra Cichlid is a plant destroyer, which conflicts with Neon Green Rasbora (Kubotai)'s requirement for live plants. Compromise where possible or prioritise the more critical need.

Both species do well with moderate (standard) water movement, so a standard filtration setup rated for the tank volume should suffice.

Frequently Asked Questions

Can Afra Cichlid and Neon Green Rasbora (Kubotai) live together?

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

What size tank do Afra Cichlid and Neon Green Rasbora (Kubotai) need?

A minimum of 247 litres (tank length at least 120 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 Afra Cichlid and Neon Green Rasbora (Kubotai) together?

Keep the aquarium between 24Β°C and 27Β°C. A target of around 25.5Β°C sits comfortably within both species' preferred ranges.

Are Afra Cichlid or Neon Green Rasbora (Kubotai) aggressive?

Afra Cichlid is semi-aggressive (8/10) and Neon Green Rasbora (Kubotai) is peaceful (1/10). The gap in aggression levels means the calmer fish may experience stress from the more assertive one.

What pH do Afra Cichlid and Neon Green Rasbora (Kubotai) need?

Their pH requirements do not overlap. Afra Cichlid prefers 7.6–8.6, while Neon Green Rasbora (Kubotai) needs 6–7.5. This makes them incompatible in the same water chemistry.

How do I manage Afra Cichlid's territorial behaviour?

Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives Afra Cichlid space to claim a territory without encroaching on the other fish's area. Adding dΓ©cor that divides the tank into distinct zones works especially well.
