Can Tanganyikan Clown Cichlid (Eretmodus) and Yoyo Loach Live Together?

Tanganyikan Clown Cichlid (Eretmodus) is a semi-aggressive species (7/10), while Yoyo Loach is generally mild-mannered (4/10). This modest difference means Tanganyikan Clown Cichlid (Eretmodus) may occasionally assert dominance over Yoyo Loach.

Tanganyikan Clown Cichlid (Eretmodus) and Yoyo Loach 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.

Worth noting: Yoyo Loach is nocturnal and will be most active after lights-out, naturally reducing daytime encounters.

The safe temperature window for both species falls between 24°C and 28°C. Aim for the midpoint of this range (around 26.0°C) for optimal comfort.

The pH requirements of Tanganyikan Clown Cichlid (Eretmodus) (8–9.5) and Yoyo Loach (6–7.5) do not overlap, making it impossible to satisfy both species simultaneously.

For general hardness, the shared comfort zone is 10–12 dGH. Regular testing will ensure conditions stay within this range.

To house Tanganyikan Clown Cichlid (Eretmodus) and Yoyo Loach together, plan for an aquarium of at least 118 litres with a minimum length of 90 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), Established Algae (Otocinclus), Sand (Sifters), Driftwood (Digestion/Hiding), Plants - Densely covered. Meeting these requirements will help both species thrive.

Both species do well with high (river/stream) water movement, so a standard filtration setup rated for the tank volume should suffice.

Tanganyikan Clown Cichlid (Eretmodus) and Yoyo Loach 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.
