Tips on Dojo Loach Care

The dojo loach, or weather loach, is a large freshwater fish that is native to northeast and central Asia. When kept in groups, the dojo loach is highly active and entertaining. These "weather fish" also tend to become restless and more active when the barometric pressure drops. Popular in aquariums, this highly adaptable fish is fairly easy to keep in captivity.

  1. Aquarium Set Up

    • Since adult fish can reach 10 inches in length, the aquarium should be about 48 inches long and as wide as possible. The dojo loach likes to dig, so a fine substrate, like sand, not course gravel, should be used in the bottom of the aquarium. The aquarium should have a very good filtration system and a secure top to prevent the fish from escaping. Water temperature should be kept between 59 and 77 degrees Fahrenheit.

    Community

    • The dojo loach is a social fish, so they should be kept in groups. No fewer than three dojo loaches should be kept together. They will lie next to one other in the sand and occasionally dart about the aquarium. Other species may be kept with the dojo loach, but avoid very small fish, aggressive species or species that are easily startled. Most temperate community fish or goldfish will survive well with the dojo loach.

    Aquarium Accessories

    • The dojo loach should have a place to hide in the aquarium. The fish is mostly nocturnal and will dig into the sand or hide during the day. Plants may be kept in the aquarium, but the loach will more than likely dig them out of the substrate. Small rocks may be placed at the base of the plant to prevent uprooting.

    Food

    • The dojo loach will eat a wide variety of foods. Sinking pellets and frozen foods, like bloodworms, are good choices. The fish will also eat frozen brine shrimp, a high-quality flake food, live earthworms and snails. The dojo loach is a docile fish that may actually eat from your hand.
