The Dojo Loach, scientifically known as Misgurnus anguillicaudatus, is a popular freshwater fish native to East Asia, including regions in China, Korea, and Japan. Known for its eel-like shape and playful behavior, the Dojo Loach is also commonly referred to as the Weather Loach due to its reputed sensitivity to changes in barometric pressure, which makes it more active or agitated before a storm.

Dojo Loaches have a long, slender body that is slightly flattened on the underside, making them excellent burrowers. Their coloration can vary from a pale, almost translucent yellow to a darker brown, with some having speckles or mottled patterns that help them blend into their natural muddy or sandy environments.

In captivity, Dojo Loaches are valued for their peaceful nature and compatibility with many other species, making them an excellent choice for community tanks. They are bottom dwellers that enjoy a soft, sandy substrate that allows them to burrow and forage without damaging their delicate barbels. They are quite hardy but thrive best in tanks with plenty of hiding spots, such as plants, rocks, and caves.

Water quality should be well-maintained with a stable temperature, and while Dojo Loaches can tolerate a range of conditions, they prefer cooler water compared to typical tropical fish. This makes them suitable for unheated tanks as long as the environment remains stable and within a comfortable range for all inhabitants.

The diet of the Dojo Loach should be varied and rich in nutrients. They are omnivorous and will accept a wide range of foods, including sinking pellets, flakes, and live or frozen foods such as bloodworms, brine shrimp, and tubifex worms. Vegetables like zucchini and cucumber slices can also be offered as part of a balanced diet.

Breeding Dojo Loaches in captivity can occur but is not common. They typically spawn in response to changes in water conditions, such as a significant drop in barometric pressure or temperature, which can be challenging to replicate intentionally in an aquarium setting.

Overall, Dojo Loaches are endearing and amusing fish that can add activity and interest to the bottom regions of the tank. Their care requirements, social nature, and fascinating behavior make them a delightful choice for both novice and experienced aquarists alike.
