The Indian knifefish or clown knifefish lives in Asia in slightly alkaline waters.
It can swim both forwards and backwards, and tends to be nocturnal. Several species
have proved marketable; one of them, Notopterus notopterus, which has only recently
been successfully bred in captivity, is used as a food source in certain parts of
the world. Size: 20-30 cm.
