Channa harcourtbutleri is a species of snakehead endemic to Inle Lake[1] and surroundings[2] in Myanmar. Locally called nga ohn-ma, among aquarists it is known as one of the "dwarf snakeheads", but no significant import for aquarists is known. It is one of the smallest species of snakehead and has a length of 20 cm. The specific name honors Sir Harcourt Butler, a British governor in the region.[1]

This was for a long time considered to be a junior synonym of Channa gachua. In fact, both species closely resemble each other. The article on its revalidation[3] only mentions three discriminating features, such as the missing ocellus in the dorsal fin of a juvenile Channa harcourtbutleri. It is suspected to be a mouthbrooder and eats a wide range of foods, including arthropods and small fish, but unlike in some relatives, no frogs.
