Can Cyprichromis Leptosoma and Red Tailed Redeye Puffer Live Together?
Cyprichromis Leptosoma and Red Tailed Redeye Puffer 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.
At a Glance
Can your tank handle Cyprichromis Leptosoma and Red Tailed Redeye Puffer?
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
Cyprichromis Leptosoma is a generally mild-mannered species (3/10), while Red Tailed Redeye Puffer is moderately assertive (6/10). This modest difference means Red Tailed Redeye Puffer may occasionally assert dominance over Cyprichromis Leptosoma.
Cyprichromis Leptosoma and Red Tailed Redeye Puffer 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: Cyprichromis Leptosoma 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 Cyprichromis Leptosoma (8–9) and Red Tailed Redeye Puffer (6–7.5) do not overlap, making it impossible to satisfy both species simultaneously.
For general hardness, the shared comfort zone is 8–15 dGH. Regular testing will ensure conditions stay within this range.
Tank Setup
To house Cyprichromis Leptosoma and Red Tailed Redeye Puffer together, plan for an aquarium of at least 200 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), Plants - Densely covered, Leaf Litter/Blackwater. 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
Cyprichromis Leptosoma and Red Tailed Redeye Puffer 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 Cyprichromis Leptosoma and Red Tailed Redeye Puffer live together?
No. This combination is not recommended. Key incompatibilities — such as critical behavioural conflicts — make cohabitation unsafe.
What size tank do Cyprichromis Leptosoma and Red Tailed Redeye Puffer need?
A minimum of 200 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 Cyprichromis Leptosoma and Red Tailed Redeye Puffer 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 Cyprichromis Leptosoma or Red Tailed Redeye Puffer aggressive?
Cyprichromis Leptosoma is generally mild-mannered (3/10) and Red Tailed Redeye Puffer is moderately assertive (6/10). Their similar temperaments generally lead to a peaceful coexistence.
What pH do Cyprichromis Leptosoma and Red Tailed Redeye Puffer need?
Their pH requirements do not overlap. Cyprichromis Leptosoma prefers 8–9, while Red Tailed Redeye Puffer needs 6–7.5. This makes them incompatible in the same water chemistry.
Will Red Tailed Redeye Puffer nip Cyprichromis Leptosoma's fins?
Red Tailed Redeye Puffer is a known fin nipper. If Cyprichromis Leptosoma has long or flowing fins, there is a real risk of fin damage. Keeping Red Tailed Redeye Puffer in a larger group can help redirect nipping behaviour toward conspecifics.
How do I manage Red Tailed Redeye Puffer's territorial behaviour?
Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives Red Tailed Redeye Puffer space to claim a territory without encroaching on the other fish's area. Adding décor that divides the tank into distinct zones works especially well.
