Can African Dwarf Frog and Cigar Shark (Mad Barb) Live Together?

African Dwarf Frog is a peaceful species (1/10), while Cigar Shark (Mad Barb) is generally mild-mannered (4/10). This modest difference means Cigar Shark (Mad Barb) may occasionally assert dominance over African Dwarf Frog.

African Dwarf Frog and Cigar Shark (Mad Barb) both frequent the 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 Nano / Bite-sized (Predation Risk) behaviour of one fish directly conflicts with the Piscivore (Eats small/nano fish) trait of the other — piscivorous fish will prey on nano-sized tank mates..

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 Dwarf Frog is nocturnal and will be most active after lights-out, naturally reducing daytime encounters. Also, African Dwarf Frog is a known jumper, so a tight-fitting lid is essential.

The safe temperature window for both species falls between 23°C and 27°C. Aim for the midpoint of this range (around 25.0°C) for optimal comfort.

Both fish can tolerate a pH between 6.5 and 7.8. 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 Dwarf Frog and Cigar Shark (Mad Barb) together, plan for an aquarium of at least 1000 litres with a minimum length of 240 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), Sand (Sifters), Plants - Densely covered. Meeting these requirements will help both species thrive.

Note a potential conflict in setup requirements: Cigar Shark (Mad Barb) is a plant destroyer, which conflicts with African Dwarf Frog's requirement for live plants. Compromise where possible or prioritise the more critical need.

African Dwarf Frog prefers Low (Still Water) flow while Cigar Shark (Mad Barb) needs High (River/Stream) flow. Consider positioning filter outlets and using baffles to create zones of different current intensity within the same tank.

Feeding time deserves special attention with this pairing. Cigar Shark (Mad Barb) is an aggressive eater that may prevent African Dwarf Frog from getting enough food.

Because Cigar Shark (Mad Barb) is a fast, competitive feeder, consider using sinking pellets or feeding at opposite ends of the setup to ensure African Dwarf Frog receives an adequate share.
