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.
Claims8
An aquarium having a transparent plastic body comprising a bottom integral with generally planar rectangular front and rear faces,
- generally vertical plastic ends bonded to side edges of the bottom and front and rear faces such that the body is water-tight,
- an opening for access into the aquarium extending between top edges of the front and rear faces, and
- a canopy containing a lamp to cover the opening,
- wherein the front and rear faces are angled acutely at a sufficient angle relative to the bottom such that when the aquarium is filled with water light inside the aquarium reflects internally off of the rear face and through the front face.
