Also called the Dojo Loach or Oriental Weather Loach, this species is native to Asia where it can be found in parts of Siberia, Korea, Japan, China and northern Vietnam. Weather Loaches tend to inhabit shallow, slow-flowing waters such as rivers, streams, swamps and backwaters. They are often found in heavily vegetated environments with mud or silt substrate and plenty of submerged roots and branches. The bodies of Weather Loaches are slender and eel-like, often exhibiting a yellow or greenish coloration with lighter undersides.
