ABSTRACT:
The invention provides an aquarium configured with its front and rear walls converging toward the top so that at tabletop or countertop height the viewer can comfortably view the aquarium from an ordinary standing position without bending over. From this viewing position the viewer cannot see through the rear face when the aquarium is filled with water, because the viewer's line of sight is at a sufficient angle that internal reflection occurs.
