Can African Clawed Frog and Black Ocellatus Live Together?
African Clawed Frog and Black Ocellatus are not recommended as tank mates due to piscivorous fish will prey on nano-sized tank mates.. 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 African Clawed Frog and Black Ocellatus?
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
African Clawed Frog is a semi-aggressive species (8/10), while Black Ocellatus is semi-aggressive (7/10). This modest difference means African Clawed Frog may occasionally assert dominance over Black Ocellatus.
Both African Clawed Frog and Black Ocellatus are highly aggressive, increasing the risk of violent confrontations.
African Clawed Frog and Black Ocellatus 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.
There is a critical concern: the Piscivore (Eats small/nano fish) behaviour of one fish directly conflicts with the Nano / Bite-sized (Predation Risk) trait of the other — piscivorous fish will prey on nano-sized tank mates..
Additional behavioural considerations to keep in mind: Shrimp eaters may also prey on very small nano fish.
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 23°C and 24°C. Aim for the midpoint of this range (around 23.5°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 8–20 dGH. Regular testing will ensure conditions stay within this range.

Tank Setup
To house African Clawed Frog and Black Ocellatus 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.

Diet & Feeding
Feeding time deserves special attention with this pairing. African Clawed Frog is a known shrimp eater and may prey on small invertebrates or nano fish like Black Ocellatus.
Because African Clawed Frog is a fast, competitive feeder, consider using sinking pellets or feeding at opposite ends of the setup to ensure Black Ocellatus receives an adequate share.

Frequently Asked Questions
Can African Clawed Frog and Black Ocellatus live together?
No. This combination is not recommended. Key incompatibilities — such as critical behavioural conflicts — make cohabitation unsafe.
What size tank do African Clawed Frog and Black Ocellatus 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 Black Ocellatus together?
Keep the aquarium between 23°C and 24°C. A target of around 23.5°C sits comfortably within both species' preferred ranges.
Are African Clawed Frog or Black Ocellatus aggressive?
African Clawed Frog is semi-aggressive (8/10) and Black Ocellatus is semi-aggressive (7/10). Their similar temperaments generally lead to a peaceful coexistence.
What pH do African Clawed Frog and Black Ocellatus 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.
How do I manage Black Ocellatus's territorial behaviour?
Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives Black Ocellatus 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.
