The horseface loach (Acantopsis dialuzona) is a freshwater fish belonging to the family Cobitidae. These loaches are endemic to Southeast Asia and can be found in countries like India, Indonesia, Thailand, Borneo, and Malaysia. Horseface loaches are also known as horsehead loaches. They are very popular as a pet species.

The horseface loach has a yellowish brown body with distinct markings. Females in this species are larger in size than the males. They are bottom dwellers and can be found in the sand or gravel bottom of slow or fast moving rivers, streams, and flooded fields. They are nocturnal in nature and become very active at night. In general, these loaches display a peaceful temperament and are a wonderful addition to any fish tank. This fish has an omnivorous diet. In a fish tank, they eat foods like fish pellets, brine shrimp, and bloodworms. However, they enjoy live food the most. If they are kept in a tank, the water temperature should be monitored, as just like the kuhli loach, the horseface loach prefers warm waters. They also survive better in water that has soft to medium hardness. The breeding behavior of this species remains largely unknown due to the lack of successful commercial breeding practices. Fortunately, their population is under no threat.
