Butis humeralis, commonly known as the dark sleeper or olive flathead-gudgeon, is a fish native to the waters of Indonesia and Indochina. Found in salt, brackish and fresh water, it reaches a standard length of 14.2 cm.[1] It closely resembles the crazy fish (Butis butis), but is more solid in build and never has two black spots at the base of its pectoral fins.[2]
