Oxyeleotris marmorata, the Marble Goby, is a widely distributed species of sleeper goby native to fresh and brackish waters of the Mekong and Chao Praya basins as well as rivers and other water bodies in Malaysia, Singapore, Indochina, Philippines and Indonesia. It is probably the largest Gobioid fish, reaching a length of 65 centimetres (26 in) SL though most do not exceed 30 centimetres (12 in) TL.
This species is an economically important fish being sought after by local commercial fisheries and is also farmed. It can also be found in the aquarium trade. It is highly popular among the Chinese community due to its fine texture, tasty white flesh and is believed to have healing properties. It is said, best eaten after surgeries or childbirths. Some say it can lead to prolonged life. In Malaysia, commercialization of this type of fish is not widely established. Demands are largely dependent on wild populations thus fetching high prices in the market.
