The ornamental design for an aquariumvideocombination, as shown in the drawings.
FIG. 1 is a perspective view of my new design of an aquarium video combination showing the remainder of an aquarium tank in dashed lines because the remainder need not form a part of the design, a video screen's viewing surface being flush with a side of the aquarium, and the right side being identical to the left side and therefore a view from the right side not being shown;
FIG. 2 is a top plan view of my new design of the aquarium video combination shown in FIG. 1, depicting the remainder of the tank in dashed lines because the remainder of the article of manufacture need not form a part of the design, the bottom being flat and unornamented and therefore a view from the bottom not being shown; and,
FIG. 3 is a perspective view of my new design of an aquarium video combination just like FIG. 1, except that the video viewing surface faces into the aquarium tank, for storage or viewing.
