2. Description of the Related Art Since a small water tank for appreciation of fish such as tropical fish has a small heat capacity, it is more susceptible to a change in temperature due to the temperature of the surrounding environment than a large water tank having a large heat capacity. For this reason, loss of fish due to excessive temperature rise of the aquarium in a very hot environment in a summer or hot region, or excessive temperature drop of the aquarium in a very cold environment in a winter or cold region. There is. For example, in the case of tropical fish, the optimum temperature is about 25 to 30 ° C., and when the room is closed to about 40 ° C. in a hot summer or the like, not only the tropical fish but also the aquatic plants in the aquarium die.

Conventionally, in order to prevent this,
In a hot environment, for example, as shown in FIG.
, A cooling heat conducting coil 32a extending therefrom is immersed in a water tank to cool water in the water tank 31, or as shown in FIG.
The large cooling device 33 is placed under the water tank 31 and the pump 3
In some cases, the cooling device 33 cools the water in the water tank 31 by a forced circulation system in combination with a circulation device using a pipe 35 or the like having a pipe 4.

[0004] As another conventional example, a water tank is installed in a place where it is easy to cool with an air conditioner, and a rise in the temperature of the water tank is suppressed by wind blown from the air conditioner. The flow of air in the water tank suppressed the temperature rise.

On the contrary, in a cold environment, as shown in FIG. 10, in order to suppress an excessive temperature drop of the water tank 31, a rod-shaped heater is placed on the sand 37 at the bottom of the water tank 31 via an electric wiring 39. 40 (insulated) was laid down.
