PURPOSE: An aquarium is provided to contain a device for moving an artificial fish in the aquarium for solving a discomfort of managing the aquarium regularly. CONSTITUTION: An aquarium includes:magnetic field generating instruments(CN1 - CNn) for generating a magnetic field in the aquarium; switches(S1 - Sn) for supplying or blocking an electric power to the magnetic field generating instrument; a switch driving unit(20) for driving the switches; a controlling unit(30) for controlling the motion of the switch driving unit; and an artificial fish(1) moving in the aquarium by being induced by the magnetic field. Herein, the beauty of the artificial fish can be raised by variously adorning such as plating or coloring the fin or the body of the artificial fish.
