One of the most identifying features of the kuhle is its slender body. At first glance, it’s very easy to mistake Kuhli Loaches for eels. Their bodies are thin and they have relatively small fins that are hard to see and they don’t have a distinguishable lateral line. While they do have a visible dorsal fin, it’s located further back than most fish. Rather than being directly in the middle of their body, it can be found on their lower third, closer to the tail. Most Kuhli Loaches are multi-colored. They do well in a non-aggressive community tank with lots of cover plants to hide in.
