Behaviour & Temperament

Neon Green Rasbora (Kubotai) is a peaceful species (1/10), while Orange Peacock is moderately assertive (6/10). This notable difference means Orange Peacock may occasionally assert dominance over Neon Green Rasbora (Kubotai).

Neon Green Rasbora (Kubotai) and Orange Peacock 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 24°C and 27°C. Aim for the midpoint of this range (around 25.5°C) for optimal comfort.

The pH requirements of Neon Green Rasbora (Kubotai) (6–7.5) and Orange Peacock (7.8–8.6) 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 Neon Green Rasbora (Kubotai) and Orange Peacock together, plan for an aquarium of at least 208 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: Plants - Densely covered, Plants - lighly covered, Leaf Litter/Blackwater, Sand (Sifters), Smooth Gravel (Sensitive Barbels). Meeting these requirements will help both species thrive.

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

Why This Pairing Usually Fails in Practice

Neon Green Rasbora (Kubotai) and Orange Peacock 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.

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

What size tank do Neon Green Rasbora (Kubotai) and Orange Peacock need?

A minimum of 208 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 Neon Green Rasbora (Kubotai) and Orange Peacock together?

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

Are Neon Green Rasbora (Kubotai) or Orange Peacock aggressive?

Neon Green Rasbora (Kubotai) is peaceful (1/10) and Orange Peacock is moderately assertive (6/10). The gap in aggression levels means the calmer fish may experience stress from the more assertive one.

What pH do Neon Green Rasbora (Kubotai) and Orange Peacock need?

Their pH requirements do not overlap. Neon Green Rasbora (Kubotai) prefers 6–7.5, while Orange Peacock needs 7.8–8.6. This makes them incompatible in the same water chemistry.
