SUMMARY OF THE INVENTION In order to solve the problems of the prior art as described above, an object of the present invention is to continuously circulate water in a fishbowl to purify water without significantly changing the water condition and environment inside the fishbowl, and to purify the water through a filter in the fishbowl. It is to provide a potted one-piece aquarium that can supply water containing protein components to the potted water. According to an embodiment of the present invention, the upper tank is open and provided with a flow control valve and the air injection port in the lower portion and a fish tank cap including a detachable fish tank cap on the upper side； The fish tank lid has a food feeding hole and a circulation discharge pipe fixing hole, and the inside of the fish tank has a plurality of discharge holes in a flat plate shape having a predetermined area, and on one side of the flat plate form a predetermined length upward. A plate having a circulating discharge pipe which protrudes and has a circulating discharge port, a filter covering the entire discharge hole of the plate, and sand is laminated on the filter to a predetermined thickness or more. A lighting device having a structure which exits through the discharge hole through the circulation discharge pipe, the circulation discharge pipe is coupled to the circulation discharge pipe fixing hole, and has a watertight structure on one side of the fish tank； A fish tank is supported under the fish tank, and has an air pipe and a water pipe therein, and has a predetermined length so that the fish tank can be supported by a predetermined distance from the ground, and has a support base in the ground direction. Safety support； An air pump for supplying air such that air is injected into the circulating discharge port inside the fish tank through an air injection port coupled with the air pipe； And a flower pot that is spaced apart from the fish tank by a predetermined distance and is
