DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. The water filtered by a filter tank (not shown) (not a sedimentation tank, a first to third circulation filter tank, or a simple known filter tank) which is not shown in the figure is attached to a water injection pipe 2 installed substantially at the center of the water tank 1. Water is supplied by a pump 3 and a watering plate 6 covered with a disk-shaped lid 4 fixed to the tip of the water injection pipe 2 and provided with a number of arc-shaped blades 5 from near the inlet to the outlet of the water injection pipe is attached. As a result, the water pumped up by the pump 4 flows from the vicinity of the inlet at the tip of the injection pipe to the outlet from the many arc-shaped blades 5 to the water surface in a number of arc-shaped outflows (in such a manner that the coming waves are broken). More air into the
In addition, the arc-shaped outflow of water gives the viewer the illusion that the runner is moving, and actually generates a swirling flow in the water, significantly increasing the dynamic visual effect of the water and increasing the swirling flow of the water. Using the habit of an ornamental fish, such as a goldfish, continuing to swim according to the gentle movement of the water, the swirling flow is further induced in the water, and the remaining bait and feces are collected at the central position. Then, the water can be discharged from a discharge port (not shown), an overflow pipe with a pinch valve, or the like, which is preferably provided at the bottom center of the water tank 1. In this way, the ornamental fish such as the goldfish continued to swim according to the gentle rotation of the water, so that the bait was good and the aquatic plants and the like grew well.
