Behaviour & Temperament
Both African Clawed Frog and Figure 8 Puffer (Brackish) are semi-aggressive species with an aggression score of 8/10. Their matching temperaments mean neither fish is likely to dominate the other in a shared aquarium.
Both African Clawed Frog and Figure 8 Puffer (Brackish) are highly aggressive, increasing the risk of violent confrontations.
African Clawed Frog and Figure 8 Puffer (Brackish) both frequent the Bottom (Substrate) and 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: African Clawed Frog 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 24°C. Aim for the midpoint of this range (around 24.0°C) for optimal comfort.
Both fish can tolerate a pH between 7.5 and 8. Maintaining a stable value within this band is more important than hitting an exact number.
For general hardness, the shared comfort zone is 10–20 dGH. Regular testing will ensure conditions stay within this range.
Crucially, these species require different water types — one needs freshwater while the other requires brackish conditions. This is a hard barrier to keeping them together.

Tank Setup
To house African Clawed Frog and Figure 8 Puffer (Brackish) 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: Smooth Gravel (Sensitive Barbels), Sand (Sifters), Shells (Breeding/Hiding). 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.

Frequently Asked Questions
Can African Clawed Frog and Figure 8 Puffer (Brackish) live together?
No. This combination is not recommended. Key incompatibilities — such as different water type needs — make cohabitation unsafe.
What size tank do African Clawed Frog and Figure 8 Puffer (Brackish) 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 African Clawed Frog and Figure 8 Puffer (Brackish) together?
Keep the aquarium between 24°C and 24°C. A target of around 24.0°C sits comfortably within both species' preferred ranges.
Are African Clawed Frog or Figure 8 Puffer (Brackish) aggressive?
African Clawed Frog is semi-aggressive (8/10) and Figure 8 Puffer (Brackish) is semi-aggressive (8/10). Their similar temperaments generally lead to a peaceful coexistence.
What pH do African Clawed Frog and Figure 8 Puffer (Brackish) need?
Both species overlap in the 7.5–8 pH range. Consistency is key — avoid sudden swings, and test regularly to stay within this window.
Will Figure 8 Puffer (Brackish) nip African Clawed Frog's fins?
Figure 8 Puffer (Brackish) is a known fin nipper. If African Clawed Frog has long or flowing fins, there is a real risk of fin damage. Keeping Figure 8 Puffer (Brackish) in a larger group can help redirect nipping behaviour toward conspecifics.
How do I manage Figure 8 Puffer (Brackish)'s territorial behaviour?
Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives Figure 8 Puffer (Brackish) 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.
