Species often confused with {name}
Catfish
Siluriformes
Key differences: While some catfish also possess barbels and are benthic, loaches typically have smaller, more numerous barbels, lack adipose fins (present in many catfish), and have a different skeletal structure, particularly in the Weberian apparatus.
Gudgeons
Gobio gobio
Key differences: Gudgeons (Cyprinidae) are also benthic and have barbels, but typically only one pair at the corners of the mouth, compared to the multiple pairs found in most loaches. Gudgeons also have larger, more prominent scales.
Eels
Anguilliformes
Key differences: Some elongated loaches might be superficially confused with eels. However, eels have continuous dorsal, caudal, and anal fins, lack pelvic fins, and have a distinct jaw structure. Loaches always possess separate fins.
