This is the aquarium that spills water but not the fish. Water cascades from the side of the bowl--creating the illusion of an aquarium that's perilously losing water--into the koi goldfish base, and back into the aquarium. A strainer at the spout prevents daredevil fish from plunging over the falls. An integrated pump continuously cycles water through a sponge and charcoal filtration system and helps maintain the proper water level inside the aquarium. Red and blue LEDs in the base cast a warm, colorful glow throughout the bowl. The five-gallon aquarium accommodates up to eight fish. The ceramic base is handpainted, glazed, and kiln-fired. Includes artificial fish and plants, a fish net, and cleaning brush. Plugs into AC. 17 3/4" H x 13 1/3" W x 12" D. (13 lbs.)
