Can African Clawed Frog and Boeseman's Rainbowfish Live Together?

African Clawed Frog is a semi-aggressive species (8/10), while Boeseman's Rainbowfish is peaceful (2/10). This notable difference means African Clawed Frog may occasionally assert dominance over Boeseman's Rainbowfish.

Large aggression gap (6 points) between African Clawed Frog and Boeseman's Rainbowfish increases stress risk for the more peaceful fish.

African Clawed Frog and Boeseman's Rainbowfish both frequent the Middle (Open Water) and Top (Surface) 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.

There is no temperature overlap between African Clawed Frog (16–24°C) and Boeseman's Rainbowfish (26–30°C). This fundamental mismatch makes long-term cohabitation impractical.

Both fish can tolerate a pH between 7 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 9–19 dGH. Regular testing will ensure conditions stay within this range.

To house African Clawed Frog and Boeseman's Rainbowfish together, plan for an aquarium of at least 200 litres with a minimum length of 120 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), Plants - lighly covered. Meeting these requirements will help both species thrive.

Note a potential conflict in setup requirements: African Clawed Frog is a plant destroyer, which conflicts with Boeseman's Rainbowfish's requirement for live plants. Compromise where possible or prioritise the more critical need.

Both species do well with low (still water) water movement, so a standard filtration setup rated for the tank volume should suffice.

African Clawed Frog and Boeseman's Rainbowfish 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.
