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

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 in the Aquarium is not known.
