The Asiatic snakehead fish ( Channa asiatica ) is one of four fish species of the genus Channa that have so far been native to the core area of China ; the other three types are Channa argus , Channa maculata, and Channa nox . It is the first snakehead fish ever described. It goes back to Linnaeus in his zoological fundamental work Systema Naturae from 1758. The location of the type cannot be found in the initial description. Its ancestral distribution area is southeast China, but it is in an unexplained way to Taiwan and even migrated to southern Japan ( Okinawa ).

Channa asiatica is a snakehead fish of medium size, ie a fish that is approx. 30–35 cm tall. He has a greenish-beige body color on which he has several "<" -like drawings that can be surrounded by shiny silver scales. In addition to these characteristic shiny scales, Channa asiatica has an ocellus on the base of the tail. He is one of the predatory fish that act as ambulance hunters. It is found in mostly stagnant waters, from where it is brought to the local markets as food fish.

Channa asiatica is also one of the first snakehead fish to be bred in an aquarium hobby. So z. B. he was bred by William T. Innes in the USA in the 1920s. Literature of the time noted this fish as nest-building snakehead fish. Offspring in Germany from 2006 showed that this fish spawns at water temperatures of 21 ° C.
