Behaviour & Temperament
African Clawed Frog is a semi-aggressive species (8/10), while MacCulloch's Rainbowfish (Dwarf Rainbowfish) is peaceful (2/10). This notable difference means African Clawed Frog may occasionally assert dominance over MacCulloch's Rainbowfish (Dwarf Rainbowfish).
Large aggression gap (6 points) between African Clawed Frog and MacCulloch's Rainbowfish (Dwarf Rainbowfish) increases stress risk for the more peaceful fish.
African Clawed Frog and MacCulloch's Rainbowfish (Dwarf 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.
To improve the chances of a peaceful coexistence in this community tank: A larger aquarium with ample hiding spots can help diffuse aggression and give the less dominant fish space to retreat.
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.
Both fish can tolerate a pH between 6.5 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.

Tank Setup
To house African Clawed Frog and MacCulloch's Rainbowfish (Dwarf Rainbowfish) together, plan for an aquarium of at least 80 litres with a minimum length of 80 cm. This recommendation combines the stricter species minimums with a community-load allowance so the pairing has realistic long-term space and filtration headroom.
Because this pairing requires extra vigilance, include plenty of hiding spots — caves, driftwood, and dense plant clusters — so the less dominant fish can retreat when needed.
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 MacCulloch's Rainbowfish (Dwarf 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.
