Common Name: Dojo Loach
Scientific Name: Misgurnus anguillicaudatus
Other Names: Weather Loach, Pond Loach, Oriental Weatherfish
The Dojo Loach, popularly known as the Weather Loach, has a slender, elongated body with a slightly flattened belly and a small, pointed head. Its barbels around the mouth are used for locating food. They can be found in a variety of colors ranging from olive-green, yellow to a golden hue. One of the most distinctive features of this loach is its ability to detect changes in atmospheric pressure, causing increased activity before storms, hence the name "Weather Loach".
Habitat and Distribution: The Dojo Loach is native to East Asia, including regions in China, Japan, and Korea. In its natural habitat, it can be found in slow-moving rivers, ponds, and rice paddies with muddy or sandy bottoms. The loach's slender body allows it to burrow into soft substrates, providing protection from predators and extreme temperatures.
Size and Lifespan: In the wild, the Dojo Loach typically reaches lengths of up to 12 inches, but in captivity, they generally grow to about 6-8 inches. With proper care, they can live up to 10 years.
Diet and Behavior: Dojo Loaches are omnivorous. In the wild, they feed on small invertebrates, aquatic insects, and plant matter. For home aquariums, they should be given a balanced diet of sinking pellets, frozen bloodworms, brine shrimp, and vegetable matter. They are active and social, often seen sifting through the substrate in search of food. Their peaceful temperament makes them ideal tankmates for many fish.
Breeding and Reproduction: While breeding in home aquariums is rare, in the wild, they lay eggs in burrows during the rainy season. Commercial breeding often involves temperature and lighting control to simulate natural conditions.
Aquarium Care and Tank Requirements: At least a 40-gallon tank is suggested. They require a soft substrate, like sand, to facilitate their burrowing behavior. Additionally, hiding spots such as caves or plants are appreciated. They thrive in well-oxygenated water with a moderate flow.
Ideal Tank Mates: Being peaceful, they coexist well with most non-aggressive species of a similar size. However, aggressive or fin-nipping fish should be avoided. They enjoy the company of their own kind and do best in groups.
Difficulty Level: Beginner to Intermediate. They are hardy and adaptable, but their specific needs, like burrowing, should be catered to for their well-being.

Additional Information:
- Their sensitivity to changes in atmospheric pressure gives them the name "Weather Loach", as they become more active before a storm.
- Though they are considered beneficial in rice paddies due to their appetite for pests, they have become invasive in some areas outside their native range.
- Always ensure that the tank has a secure lid, as they are known to be skilled escape artists.
