Can Red Tailed Redeye Puffer and Telmatochromis brichardi Live Together?
Red Tailed Redeye Puffer and Telmatochromis brichardi 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 Red Tailed Redeye Puffer and Telmatochromis brichardi?
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 Red Tailed Redeye Puffer and Telmatochromis brichardi are moderately assertive species with an aggression score of 6/10. Their matching temperaments mean neither fish is likely to dominate the other in a shared aquarium.
Red Tailed Redeye Puffer and Telmatochromis brichardi both frequent the Bottom (Substrate) 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: Shrimp eaters may also prey on very small nano fish.
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 Red Tailed Redeye Puffer (6–7.5) and Telmatochromis brichardi (8–9.3) do not overlap, making it impossible to satisfy both species simultaneously.
For general hardness, the shared comfort zone is 10–15 dGH. Regular testing will ensure conditions stay within this range.
Tank Setup
To house Red Tailed Redeye Puffer and Telmatochromis brichardi together, plan for an aquarium of at least 75 litres with a minimum length of 60 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, Leaf Litter/Blackwater, Sand (Sifters), Shells (Breeding/Hiding), 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
Red Tailed Redeye Puffer and Telmatochromis brichardi 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 Red Tailed Redeye Puffer and Telmatochromis brichardi live together?
No. This combination is not recommended. Key incompatibilities — such as critical behavioural conflicts — make cohabitation unsafe.
What size tank do Red Tailed Redeye Puffer and Telmatochromis brichardi need?
A minimum of 75 litres (tank length at least 60 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 Red Tailed Redeye Puffer and Telmatochromis brichardi 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 Red Tailed Redeye Puffer or Telmatochromis brichardi aggressive?
Red Tailed Redeye Puffer is moderately assertive (6/10) and Telmatochromis brichardi is moderately assertive (6/10). Their similar temperaments generally lead to a peaceful coexistence.
What pH do Red Tailed Redeye Puffer and Telmatochromis brichardi need?
Their pH requirements do not overlap. Red Tailed Redeye Puffer prefers 6–7.5, while Telmatochromis brichardi needs 8–9.3. This makes them incompatible in the same water chemistry.
Will Red Tailed Redeye Puffer nip Telmatochromis brichardi's fins?
Red Tailed Redeye Puffer is a known fin nipper. If Telmatochromis brichardi 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.
