Can African Clawed Frog and Betta Macrostoma Live Together?

African Clawed Frog is a semi-aggressive species (8/10), while Betta Macrostoma is moderately assertive (6/10). This modest difference means African Clawed Frog may occasionally assert dominance over Betta Macrostoma.

African Clawed Frog and Betta Macrostoma both frequent the Bottom (Substrate), 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.

Additional behavioural considerations to keep in mind: Hyperactive swimmers can stress shy, slow-moving species through constant motion. Aggressive eaters may outcompete shy fish for food, leading to malnutrition.

Worth noting: African Clawed Frog is a known jumper, so a tight-fitting lid is essential.

The safe temperature window for both species falls between 20°C and 24°C. Aim for the midpoint of this range (around 22.0°C) for optimal comfort.

The pH requirements of African Clawed Frog (6.5–8) and Betta Macrostoma (4–6) do not overlap, making it impossible to satisfy both species simultaneously.

For general hardness, the shared comfort zone is 5–5 dGH. Regular testing will ensure conditions stay within this range.

To house African Clawed Frog and Betta Macrostoma together, plan for an aquarium of at least 80 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), Leaf Litter/Blackwater, Driftwood (Digestion/Hiding), Plants - Floating. 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 Clawed Frog and Betta Macrostoma 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.

Feeding time deserves special attention with this pairing. African Clawed Frog is an aggressive eater that may prevent Betta Macrostoma from getting enough food.

Because African Clawed Frog is a fast, competitive feeder, consider using sinking pellets or feeding at opposite ends of the setup to ensure Betta Macrostoma receives an adequate share.
