Can Mbu Puffer and Red-Tail Catfish Live Together?
Keeping Mbu Puffer and Red-Tail Catfish together is possible but requires caution, though some care is needed. Provide a spacious tank of at least 4560 litres with plenty of hiding spots to reduce stress. Monitor behaviour closely, especially during the first few weeks.
At a Glance
Behaviour & Temperament
Both Mbu Puffer and Red-Tail Catfish are semi-aggressive species with an aggression score of 7/10. Their matching temperaments mean neither fish is likely to dominate the other in a shared aquarium.
Both Mbu Puffer and Red-Tail Catfish are highly aggressive, increasing the risk of violent confrontations.
Mbu Puffer and Red-Tail Catfish 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.
Worth noting: Red-Tail Catfish is nocturnal and will be most active after lights-out, naturally reducing daytime encounters.
To improve the chances of a peaceful coexistence in this community tank: Keep fin nippers in larger groups to distribute nipping behaviour among conspecifics rather than tank mates.
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.
Both fish can tolerate a pH between 7 and 7.5. Maintaining a stable value within this band is more important than hitting an exact number.
For general hardness, the shared comfort zone is 10–15 dGH. Regular testing will ensure conditions stay within this range. An aquarium test kit is recommended for monitoring.
Tank Setup
To house Mbu Puffer and Red-Tail Catfish together, plan for an aquarium of at least 4560 litres with a minimum length of 300 cm. This accounts for the larger species' space requirements with an additional 20 % buffer to reduce territorial tension.
Because this pairing requires extra vigilance, include plenty of hiding spots — caves, driftwood, and dense plant clusters — so the less dominant fish can retreat when needed.
Specific environmental needs for this combination include: Sand (Sifters), Shells (Breeding/Hiding), Smooth Gravel (Sensitive Barbels), Driftwood (Digestion/Hiding). 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.

Frequently Asked Questions
Can Mbu Puffer and Red-Tail Catfish live together?▾
They can coexist, but the pairing requires careful monitoring. Provide ample space (at least 4560 litres), plenty of hiding spots, and watch for signs of stress or aggression.
What size tank do Mbu Puffer and Red-Tail Catfish need?▾
A minimum of 4560 litres (tank length at least 300 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 Mbu Puffer and Red-Tail Catfish 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 Mbu Puffer or Red-Tail Catfish aggressive?▾
Mbu Puffer is semi-aggressive (7/10) and Red-Tail Catfish is semi-aggressive (7/10). Their similar temperaments generally lead to a peaceful coexistence.
What pH do Mbu Puffer and Red-Tail Catfish need?▾
Both species overlap in the 7–7.5 pH range. Consistency is key — avoid sudden swings, and test regularly to stay within this window.
Will Mbu Puffer nip Red-Tail Catfish's fins?▾
Mbu Puffer is a known fin nipper. If Red-Tail Catfish has long or flowing fins, there is a real risk of fin damage. Keeping Mbu Puffer in a larger group can help redirect nipping behaviour toward conspecifics.
Does Red-Tail Catfish being nocturnal affect compatibility?▾
Red-Tail Catfish is most active after lights-out, which naturally reduces daytime encounters with its tank mate. This can actually be beneficial, as both fish get undisturbed time to feed and explore. Just ensure food reaches Red-Tail Catfish during evening hours.
