PURPOSE: A small fish globe is provided which is easily washed and refilled, and is excellent in an aesthetic view because of the electric apparatus not being observed outside. CONSTITUTION: A fish globe comprises a body(1), an establishment case(2), a lid(3), a temperature controlling apparatus(4) and an oxygen generator(5), wherein a binding hole(6) of the establishment case is formed in the lower part of the body(1), the binding projections(7) are formed in the establishment case(2), the body(1) contains a linking hose(8) connected with the oxygen generator(5) and preventing the countercurrent of water in the inside. The binding projections(7) can be inserted into the binding hole of the establishment case, as the body (1) is stably set on the establishment case(2). The countercurrent of water in the connecting hose is prevented by an outer tube(9) and an inner tube(10), wherein the outer tube contains large perforated holes(11) having a diameter of about 0.5mm and the inner tube(10) contains fine holes, but the inner tube is made of elastic materials so that air leaks from the expanded fine holes as the air is filled over a certain level and the fine holes is blocked as the air pressure decreases.
