Behaviour & Temperament

Dojo Loach (Weather Loach) is a peaceful species (2/10), while Florida Flagfish is moderately assertive (5/10). This modest difference means Florida Flagfish may occasionally assert dominance over Dojo Loach (Weather Loach).

Dojo Loach (Weather Loach) and Florida Flagfish 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: Dojo Loach (Weather Loach) is a known jumper, so a tight-fitting lid is essential.

Water Parameters

The safe temperature window for both species falls between 18°C and 24°C. Aim for the midpoint of this range (around 21.0°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 10–15 dGH. Regular testing will ensure conditions stay within this range. An aquarium test kit is recommended for monitoring.

Tank Setup

To house Dojo Loach (Weather Loach) and Florida Flagfish 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), Established Algae (Otocinclus), Plants - Densely covered. Meeting these requirements will help both species thrive.

Note a potential conflict in setup requirements: Dojo Loach (Weather Loach) is a plant destroyer, which conflicts with Florida Flagfish's requirement for live plants. Compromise where possible or prioritise the more critical need.

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