An L-shaped support is coupled between a bottom wall and a top wall of the housing. The top wall of the housing may support an aquarium. A shelf is coupled between the bottom and top walls of the housing. A display support is coupled to the housing. The display support extends upwardly from the housing. A mount is coupled to the display support so the mount may support a display. A pump is coupled to the housing. The pump is operationally coupled to the aquarium so the pump urges a fluid into the aquarium. A trough coupled to the housing. The trough may capture fluid from the aquarium. A drain is coupled to the housing. The drain is operationally coupled to the trough so the drain collects the fluid.
