A device for feeding fish that was supplied and returned to the inside of the aquarium was also used.
It is known from Japanese Patent No. 21589.

<Problems to be solved by the invention> Generally, when filtering water in an aquarium, if water is passed through a filter material such as non-woven fabric or glass wool, fine dust and impurities contained in the water will be contained in this filter material. Since it is removed, physical filtration works, and when water is passed through the gravel or sand, the microorganisms attached to the gravel purify the water, and thus biological filtration works. However, the conventional water tank having the above-mentioned filtration tank has a complicated structure and is expensive, and has poor physical and biological filtration effects, so that the water in the water tank must be frequently replaced.

Moreover, not only is it extremely time-consuming and time-consuming to exchange water, but the water tank may be damaged or fish kept dead during the water exchange operation.
