Can African Dwarf Frog and Monster Wolf Fish (Aimara) Live Together?

African Dwarf Frog is a peaceful species (1/10), while Monster Wolf Fish (Aimara) is highly aggressive (10/10). This notable difference means Monster Wolf Fish (Aimara) may occasionally assert dominance over African Dwarf Frog.

Large aggression gap (9 points) between African Dwarf Frog and Monster Wolf Fish (Aimara) increases stress risk for the more peaceful fish.

African Dwarf Frog and Monster Wolf Fish (Aimara) both frequent the Bottom (Substrate) 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: Aggressive fish may bully and stress shy, slow-moving species. Hyperactive swimmers can stress shy, slow-moving species through constant motion.

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 7.5. 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 Monster Wolf Fish (Aimara) together, plan for an aquarium of at least 1500 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, Driftwood (Digestion/Hiding). Meeting these requirements will help both species thrive.

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