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

Kenyi Cichlid is a highly aggressive species (9/10), while Neon Green Rasbora (Kubotai) is peaceful (1/10). This notable difference means Kenyi Cichlid may occasionally assert dominance over Neon Green Rasbora (Kubotai).

Large aggression gap (8 points) between Kenyi Cichlid and Neon Green Rasbora (Kubotai) increases stress risk for the more peaceful fish.

Kenyi 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.

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 Kenyi Cichlid (7.8–8.6) 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.

To house Kenyi Cichlid and Neon Green Rasbora (Kubotai) together, plan for an aquarium of at least 256 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: Kenyi 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.

Kenyi Cichlid and Neon Green Rasbora (Kubotai) are the kind of pair that can look acceptable in a shop but become a maintenance problem at home. The main risk is not a single number in the chart; it is the way incompatible behavior, water needs, or pressure on space compounds over time once both fish are established in the same tank.
