Gyrinocheilus aymonieri is a freshwater fish native to large parts of Southeast Asia. It is of interest as a local food source and for the aquarium trade. Its common names include honey sucker, sucking loach and Chinese algae eater.
G. aymonieri is found in the Chao Phraya basin, northern Malay Peninsula, Mekong basin (in Cambodia, Yunnan province in China, Laos, Thailand, and Vietnam), Mae Klong basin and the Xe Bang Fai River. It is most often seen in large rivers, occasionally entering flooded fields. The fish spends most of its time on flat surfaces, such as rocks, in flowing water, using its unusually formed inferior mouth to attach itself to rocks in stronger flows.
The fish are sold in local markets as a food source and small fish are used in preparation of prahok.
The scientific name commemorates the French linguist and explorer Étienne Aymonier (1844–1929).

starts withG. aymonieri has been recorded as reaching at least 28 cm (11 in) SL and is the only species in the genus to have 9 branched dorsal rays and 36–40 lateral line scales. The mouth is inferior with a special "sucker" modification which allows the fish to attach itself to smooth surfaces. No barbels are present.
Wild type colour varies from pale grey to olive, with darker markings along the lateral line which vary from a solid stripe with alternating higher and lower extensions to uneven dots. The belly is usually paler than the base colour. Some darker markings may also be observed along the back and on the caudal fin, but no dark markings occur on the pelvic and anal fins.
