They are also known as the Coolie Loach, the Leopard Loach or the Cinnamon Loach. This Loach has an eel body shape body that is yellow to pink in color, with multiple dark brown bands or stripes that partially or fully encircle the body and they are scavengers making them great aquarium cleaners. The advantage of this Loach over others is its size. They have a head with no scales, and they are very sensitive to medications. The coolie loach is most active at twilight and at nighttime, both in nature and in the home aquarium, while remaining hidden during the day.
