The Weather Loach (Misgurnus anguillicaudatus), is sometimes referred to as the Japanese Weatherfish and are one of the few species of bottom dwelling fish available to coldwater aquariums.
The Weather Loach gets its name from the fact that it swims to the surface when it rains. It is eel like in appearance and will happily clean up the tank of fed left by goldfish. It also likes to burrow through the substrate keeping it fresh.
This fish requires a large tank and the bottom needs to be covered with fine sand or pea gravel. About 6cm deep substrate will be sufficient for this fish. It will benefit from bogwood and plants and regular checks need to be made on plants because this fish will uproot them from time to time.
The Weather Loach grows to 20cm in length and originates from China and Japan. It lives in ponds, rivers and lakes as well as stagnant bodies of freshwater. It does not often breed in captivity and is an egg scaterer. It can be fed sinking tablets or frozen food. Temperature should range from between 10-22 degrees centigrade and this fish will benefit from neutral to moderately alkaline water.
With weekly water chemistry checks this fish should not be hard to keep.
