Chela

The neon hatchet fish, Chela cachius, is a deep-bodied cyprinid mostly recorded from the Ganges and Brahmaputra systems of India and Bangladesh. Its extremely deep body means it is unlikely to be confused with any related species, and it is the only valid member of the genus. A habitat generalist, it is an active schooling fish that is best kept in a group of at least 8-10 in a tank with a tightly-fitting cover, since it is an accomplished jumper.
