Can African Clawed Frog and Betta Macrostoma Live Together?
African Clawed Frog and Betta Macrostoma are not recommended as tank mates due to conflicting pH requirements. 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 Betta Macrostoma?
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 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.
Water Parameters
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.

Tank Setup
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.

Diet & Feeding
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.

Frequently Asked Questions
Can African Clawed Frog and Betta Macrostoma 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 Betta Macrostoma need?
A minimum of 80 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 Betta Macrostoma together?
Keep the aquarium between 20°C and 24°C. A target of around 22.0°C sits comfortably within both species' preferred ranges.
Are African Clawed Frog or Betta Macrostoma aggressive?
African Clawed Frog is semi-aggressive (8/10) and Betta Macrostoma is moderately assertive (6/10). Their similar temperaments generally lead to a peaceful coexistence.
What pH do African Clawed Frog and Betta Macrostoma need?
Their pH requirements do not overlap. African Clawed Frog prefers 6.5–8, while Betta Macrostoma needs 4–6. This makes them incompatible in the same water chemistry.
How do I manage Betta Macrostoma's territorial behaviour?
Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives Betta Macrostoma 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.
