Acantopsis is a genus of freshwater fishes, commonly known as horseface loaches or banana-root fishes, in the family Cobitidae. Fishes of the genus Acantopsis inhabit sandy riverbeds throughout Southeast Asia and are most diverse in the Mekong River in Thailand, Laos, and Cambodia wherein five species are known to occur. The common horseface loach, A. rungthipae, is popular in the aquarium trade.
