Combined aquarium and fish pond - has open bottom of tank immersed in pond water enabling fish to enter for viewing

摘要

The fishpond which can be combined with an aquarium has the aquarium tank installed e.g. at one end and supported at a suitable height so that the fish can enter the tank from the pond. This enables the fish to be more easily seen. The tank can be rectangular, dome shaped etc., under the water level of the pond. Air can be sucked from the space above the water inside the aquarium by a suction pump, so that the water level in the aquarium is at a higher level than that of the pond.
