Pond loach
The pond loach, , or oriental/Japanese weather loach (''Misgurnus anguillicaudatus''), is a freshwater fish in the loach family Cobitidae. They are native to East Asia but are also popular as an aquarium fish and introduced elsewhere in Asia and to Europe and North America.〔 The alternate name weather loach is shared with several other Cobitidae, including the other members of the genus ''Misgurnus'' and the spotted weather loach (''Cobitis taenia'', commonly known as spined loach). This term comes from their ability to detect changes in barometric pressure and react with frantic swimming or standing on end. This is because before a storm the barometric pressure changes, and this is known to make these fish more active. The pond loach also comes in a variety of colors, such as pink, orange, and gray.
==Description==
Like many other loaches, pond loaches are slender and eel-like. They can vary in colour from yellow to olive green, to a common light brown or grey with lighter undersides. The mouth of the loach is surrounded by three sets of barbels. It uses them to sift through silt or pebbles to find food. It also uses them to dig under gravel and sand to conceal itself out of nervousness or defence unlike the other loaches who use the spines beneath the eyes.
They can grow up to 12 inches (30.5 cm) long. The fish are bottom-dwelling scavengers, feeding mainly on organic material such as algae. Pond loaches are omnivorous and may also feed on tubifex worms and other small aquatic organisms. By producing a layer of mucus to keep themselves damp they can survive short periods of desiccation. They are very hardy fish that can live in poor quality water.
