Dojo Loach (Weather Loach)

The Dojo Loach (Weather Loach), scientifically known as Misgurnus anguillicaudatus, belongs to the Loaches family group. Adults reach a maximum size of approximately 25 cm and have a eel body shape with a fast growth rate. Classified as peaceful, this species primarily occupies the bottom zone of the aquarium and produces a high level of biological waste.

To thrive, the Dojo Loach (Weather Loach) requires a freshwater only aquarium with a minimum volume of 200 litres and a tank length of at least 120 cm. Water temperature should be maintained between 10°C and 24°C, with a pH range of 6.5–8 and a general hardness of 5–15 dGH. A moderate water flow is preferred.

The Dojo Loach (Weather Loach) is a rewarding species to keep, provided its core environmental needs are met. This species is available in 2 varieties: Standard Adult and Juvenile (Grow-out). Each may differ slightly in size, temperament, or care needs, so it is worth checking the specific requirements of the variety you plan to keep.

When setting up an aquarium for the Dojo Loach (Weather Loach), a moderate water flow best suits their natural preferences. Because this species occupies the bottom zone, the aquarium layout should prioritise sufficient floor space with hiding spots among rocks, wood, or dense planting. Useful additions include a sand substrate to accommodate their sifting behaviour. Keepers should note that a tight-fitting lid is essential, as this species is a known jumper, expect substrate disturbance, so lightweight décor should be secured, and live planted layouts may be difficult to maintain, as this species tends to uproot or consume vegetation.

Classified as peaceful, the Dojo Loach (Weather Loach) is a social species that requires the company of its own kind to thrive. When choosing tankmates, snails will be treated as food rather than tankmates and their energetic swimming style may stress more sedentary or timid species. Selecting tankmates that favour different water layers from the bottom zone can help reduce competition and territorial overlap.

Dojo Loach (Weather Loach) is best for a fishkeeper who wants a species that can settle into a calmer community setup and can provide a keeper who can commit to a proper group of at least 3. It makes the most sense for a hobbyist who will actually build around its needs, especially sand.

The most common mistake is treating Dojo Loach (Weather Loach) like any other community fish and skipping the soft sand it needs to forage safely. Another frequent problem is underestimating its social needs. A token pair or trio often behaves very differently from a real group.
