Though most frequently called the Black Kuhli Loach, this fish is also known as the Chocolate Kuhli or the Java Loach. These fish are fairly widespread, having been found in parts of Java, Peninsular Malaysia, Indonesia and the islands of Borneo and Sumatra. These fish tend to inhabit shallow, slow-moving waters such as swamps, backwaters and forest streams. Black Kuhli Loaches are often found in blackwater environments and waters that are shaded by marginal or submerged vegetation.
