ABSTRACT:
A sealed-type aquarium device capable of permitting a viewer to feel unexpected and marvelous interest in addition to enjoyment through observation of fish. The aquarium device includes a sealed aquarium body which is constructed so as to prevent air from being introduced into the aquarium body. Water cleaned through a filtering unit is fed under pressure through a feed pipe to the aquarium body by a feed pump, so that a water pressure in the aquarium body is increased to cause water polluted in the aquarium body to be forcibly discharged through a drain pipe to the filtering unit. The aquarium body may be formed into any desired shape.
