Can African Clawed Frog and Forktail Blue-eye Live Together?

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

Large aggression gap (6 points) between African Clawed Frog and Forktail Blue-eye increases stress risk for the more peaceful fish.

African Clawed Frog and Forktail Blue-eye 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.

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.

The safe temperature window for both species falls between 24°C and 24°C. Aim for the midpoint of this range (around 24.0°C) for optimal comfort.

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 5–15 dGH. Regular testing will ensure conditions stay within this range.

To house African Clawed Frog and Forktail Blue-eye 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), Plants - Densely 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 Forktail Blue-eye'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 Forktail Blue-eye 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 a known shrimp eater and may prey on small invertebrates or nano fish like Forktail Blue-eye.

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