Can Green Neon Tetra and Xenotilapia ochrogenys Live Together?

Reviewed by Guidarium Editorial DeskUpdated May 11, 2026
Not Recommended

Green Neon Tetra and Xenotilapia ochrogenys 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.

Can your tank handle Green Neon Tetra and Xenotilapia ochrogenys?

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

Green Neon Tetra is a peaceful species (0/10), while Xenotilapia ochrogenys is generally mild-mannered (4/10). This notable difference means Xenotilapia ochrogenys may occasionally assert dominance over Green Neon Tetra.

In terms of spatial distribution, Green Neon Tetra prefers the Middle (Open Water) zone, whereas Xenotilapia ochrogenys occupies the Bottom (Substrate) zone. Because they use different levels of the water column, territorial disputes are less likely and the tank will appear more balanced.

Additional behavioural considerations to keep in mind: Hyperactive swimmers can stress shy, slow-moving species through constant motion.

Worth noting: Xenotilapia ochrogenys 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 28°C. Aim for the midpoint of this range (around 26.0°C) for optimal comfort.

The pH requirements of Green Neon Tetra (4.5–6.5) and Xenotilapia ochrogenys (8–9) do not overlap, making it impossible to satisfy both species simultaneously.

Hardness requirements are incompatible: Green Neon Tetra needs 1–8 dGH while Xenotilapia ochrogenys requires 10–25 dGH.

Tank Setup

To house Green Neon Tetra and Xenotilapia ochrogenys 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: Leaf Litter/Blackwater, Plants - Densely covered, Plants - Floating, Sand (Sifters), 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.

Why This Pairing Usually Fails in Practice

Green Neon Tetra and Xenotilapia ochrogenys 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.

Frequently Asked Questions

Can Green Neon Tetra and Xenotilapia ochrogenys live together?

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

What size tank do Green Neon Tetra and Xenotilapia ochrogenys 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 Green Neon Tetra and Xenotilapia ochrogenys together?

Keep the aquarium between 24°C and 28°C. A target of around 26.0°C sits comfortably within both species' preferred ranges.

Are Green Neon Tetra or Xenotilapia ochrogenys aggressive?

Green Neon Tetra is peaceful (0/10) and Xenotilapia ochrogenys is generally mild-mannered (4/10). The gap in aggression levels means the calmer fish may experience stress from the more assertive one.

What pH do Green Neon Tetra and Xenotilapia ochrogenys need?

Their pH requirements do not overlap. Green Neon Tetra prefers 4.5–6.5, while Xenotilapia ochrogenys needs 8–9. This makes them incompatible in the same water chemistry.
