Can Brown Puffer and Telmatochromis dhonti Live Together?
Brown Puffer and Telmatochromis dhonti 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 Brown Puffer and Telmatochromis dhonti?
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
Brown Puffer is a highly aggressive species (9/10), while Telmatochromis dhonti is semi-aggressive (8/10). This modest difference means Brown Puffer may occasionally assert dominance over Telmatochromis dhonti.
Both Brown Puffer and Telmatochromis dhonti are highly aggressive, increasing the risk of violent confrontations.
Brown Puffer and Telmatochromis dhonti 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: Two territorial species may clash over territory, especially in smaller tanks. Two aggressive species housed together increases risk of fighting.
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 Brown Puffer (6.5–7.5) and Telmatochromis dhonti (7.8–9) 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 Brown Puffer and Telmatochromis dhonti together, plan for an aquarium of at least 120 litres with a minimum length of 90 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), Shells (Breeding/Hiding), Plants - Densely covered. 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
Brown Puffer and Telmatochromis dhonti 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 Brown Puffer and Telmatochromis dhonti live together?
No. This combination is not recommended. Key incompatibilities — such as critical behavioural conflicts — make cohabitation unsafe.
What size tank do Brown Puffer and Telmatochromis dhonti need?
A minimum of 120 litres (tank length at least 90 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 Brown Puffer and Telmatochromis dhonti 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 Brown Puffer or Telmatochromis dhonti aggressive?
Brown Puffer is highly aggressive (9/10) and Telmatochromis dhonti is semi-aggressive (8/10). Their similar temperaments generally lead to a peaceful coexistence.
What pH do Brown Puffer and Telmatochromis dhonti need?
Their pH requirements do not overlap. Brown Puffer prefers 6.5–7.5, while Telmatochromis dhonti needs 7.8–9. This makes them incompatible in the same water chemistry.
Will Brown Puffer nip Telmatochromis dhonti's fins?
Brown Puffer is a known fin nipper. If Telmatochromis dhonti has long or flowing fins, there is a real risk of fin damage. Keeping Brown Puffer in a larger group can help redirect nipping behaviour toward conspecifics.
How do I manage Brown Puffer's territorial behaviour?
Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives Brown 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.
