The fish is known for its longevity, beautiful coloration, amazing patterns and markings, and unique shape.Borneo suckers are bottom dwellers and they enjoy cool, oxygen-rich, swift waters similar to that of their natural habitat, in addition to ample algae and biofilmBorneo suckers (Gastromyzon app.) are native to the Borneo region of South east Asia (Malaysia: Sabah & Sarawak; Indonesia: Kalimantan Barat, Kalimantan Timur; and Brunei Darussalam: Temburong district).They inhabit shallow, swift streams and rivers containing clear, cool, and oxygen-rich water.The habitat is characterized by the abundance of sandy substrates, rocks, gravels, and huge boulders; these are usually slimy as a result of algal growth which serves as their main food source.The temperature in this area is fairly cool due to the presence of tall trees, on the other hand, submerged vegetation is scarce.
Borneo suckers are generally peaceful and interactive. They are mostly seen clinging tightly to large rocks in the tank— either relaxing or consuming algae growing on them. Other times, they may be found lying around or climbing the tank glass.
