Can Dojo Loach (Weather Loach) and Senegal Bichir Live Together?

Dojo Loach (Weather Loach) is a peaceful species (2/10), while Senegal Bichir is moderately assertive (6/10). This notable difference means Senegal Bichir may occasionally assert dominance over Dojo Loach (Weather Loach).

Dojo Loach (Weather Loach) and Senegal Bichir 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: Senegal Bichir is nocturnal and will be most active after lights-out, naturally reducing daytime encounters. Also, Dojo Loach (Weather Loach) is a known jumper, so a tight-fitting lid is essential.

There is no temperature overlap between Dojo Loach (Weather Loach) (10–24°C) and Senegal Bichir (25–29°C). This fundamental mismatch makes long-term cohabitation impractical.

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. An aquarium test kit is recommended for monitoring.

To house Dojo Loach (Weather Loach) and Senegal Bichir together, plan for an aquarium of at least 240 litres with a minimum length of 120 cm. This accounts for the larger species' space requirements with an additional 20 % buffer to reduce territorial tension.

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: Sand (Sifters), Smooth Gravel (Sensitive Barbels), Driftwood (Digestion/Hiding). Meeting these requirements will help both species thrive.

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