Can African Dwarf Frog and Pearly Ocellatus Live Together?

African Dwarf Frog is a peaceful species (1/10), while Pearly Ocellatus is semi-aggressive (7/10). This notable difference means Pearly Ocellatus may occasionally assert dominance over African Dwarf Frog.

Large aggression gap (6 points) between African Dwarf Frog and Pearly Ocellatus increases stress risk for the more peaceful fish.

African Dwarf Frog and Pearly 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.

Worth noting: African Dwarf Frog is nocturnal and will be most active after lights-out, naturally reducing daytime encounters. Also, African Dwarf Frog is a known jumper, so a tight-fitting lid is essential.

The safe temperature window for both species falls between 24°C and 27°C. Aim for the midpoint of this range (around 25.5°C) for optimal comfort.

The pH requirements of African Dwarf Frog (6.5–7.8) and Pearly Ocellatus (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.

To house African Dwarf Frog and Pearly Ocellatus together, plan for an aquarium of at least 38 litres with a minimum length of 45 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), Plants - Densely covered, 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.

African Dwarf Frog and Pearly Ocellatus 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.
