Can Green Neon Tetra and Malaya Shrimp Live Together?

Reviewed by Guidarium Editorial DeskUpdated May 6, 2026
Not Recommended

Green Neon Tetra and Malaya Shrimp 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 Green Neon Tetra and Malaya Shrimp?

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

Both Green Neon Tetra and Malaya Shrimp are peaceful species with an aggression score of 0/10. Their matching temperaments mean neither fish is likely to dominate the other in a shared aquarium.

Green Neon Tetra and Malaya Shrimp 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.

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

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 Malaya Shrimp (6.8–7.8) do not overlap, making it impossible to satisfy both species simultaneously.

For general hardness, the shared comfort zone is 4–8 dGH. Regular testing will ensure conditions stay within this range.

Tank Setup

To house Green Neon Tetra and Malaya Shrimp together, plan for an aquarium of at least 38 litres with a minimum length of 45 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, Established Algae (Otocinclus). 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 Malaya Shrimp 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 Malaya Shrimp 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 Malaya Shrimp need?

A minimum of 38 litres (tank length at least 45 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 Malaya Shrimp 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 Malaya Shrimp aggressive?

Green Neon Tetra is peaceful (0/10) and Malaya Shrimp is peaceful (0/10). Their similar temperaments generally lead to a peaceful coexistence.

What pH do Green Neon Tetra and Malaya Shrimp need?

Their pH requirements do not overlap. Green Neon Tetra prefers 4.5–6.5, while Malaya Shrimp needs 6.8–7.8. This makes them incompatible in the same water chemistry.
