General Body Form:The body of the Horsefaced loach is long and flattened with a snout that is characteristically long, sloping downwards, resembling a Horses’ head. Females generally are longer then the male and have a larger abdominal area. Gravid females are noticeably plumper and longer then the males.


    Many color and pattern variations are known due to it’s wide geographic distribution. The most commonly sold in the US are silver/grey bodies with black stripes along it’s back and flanks. .


    This species is an active burrower, so it is highly recommended that the aquarium substrate be fine-grained sand with a minimum depth of 3″. Another reason for fine-grained sand is that these loaches often filter their food through their gills. Most foods are accepted, such as sinking wafers and flake food. Frozen or live bloodworms, insect larvae, brine shrimp are a welcomed treat. This species will not compete for their food, so it is advisable to add extra for the bottom-dwellers. Plants can be uprooted as a result of the loaches’ burrowing, so anchoring or deep rooting them is also advisable. Rocks, caves , plants , and wood can be used as cover. This species of loaches are a schooling fish and are best kept in a group of 3 or more.


    The Region in which the Horsefaced loach inhabits is in rapid and slow moving rivers with sandy and rocky bottoms.

Breeding:Breeding in the Aquarium is not known.
