  In the second stacking mode, the inner dimension of the upper section of the long side plate is larger than the outer dimension of the lower section of the long side plate, and the inner dimension of the upper section of the short side plate is outside the lower section of the short side plate. Since it is larger than the dimension, the lower stage of the upper aquarium fish tank can be stored in the upper stage of the lower aquarium fish tank, and thus a plurality of aquarium fish tanks can be prevented from becoming bulky.

  According to the invention as recited in the aforementioned Item [2], an upper edge step is formed on each of the upper edge inner surfaces of the long side plate and the short side plate. Positioning becomes stable.

  According to the invention [3], since the aquarium for aquarium fish is formed of styrofoam, the heat insulation effect is high and the water temperature can be stabilized even when installed mainly outdoors.

  According to the invention as recited in the aforementioned Item [4], the upper edge of the long side plate or the short side plate is provided with an overflow groove in which water overflows out of the ornamental fish tank, so that the water is newly provided in the ornamental fish tank. By injecting water into the water, the conventional water is discharged out of the ornamental fish tank through the overflow groove, and the time required for replacing water is greatly reduced. Also, when the ornamental fish tank is installed outdoors, a sudden change in water quality can be prevented and the water quality can be stabilized when the water level rises due to sudden rainwater such as concentrated torrential rain.

  According to the invention as recited in the aforementioned Item [5], since the overflow groove is formed in a tapered shape in which the groove width becomes narrower from the inside to the outside, for example, when the sponge is arranged in the overflow groove, water pressure is applied to the sponge. Even if the sponge is pushed out of the aquarium fish tank, the sponge is blocked by the narrow outer portion and can be prevented from falling out of the aquarium fish tank. In addition, the fry and the juvenile are blocked by the narrow outer portion and can be prevented from falling out of the water tank.
