ABSTRACT:
A fish aquarium having structure that produces an improved display for fish and other objects contained therein. The front wall is formed of a transparent material and it has a vertically oriented lower section, a vertically oriented upper section and and angularly oriented central section that connects the upper and lower sections that are laterally offset a predetermined distance from each other. The angularly oriented central section along with the water in the aquarium produces an optical illusion that the material and objects supported in the bottom of the aquarium have a front to rear upwardly oriented appearance. A hermetically sealed elongated light housing is mounted inside the aquarium adjacent the intersection of its top wall and the upper section of its front wall. The florescent lamp in the light housing directs all of its light only in the downward and rearwardly direction which prevents the production of a glare off the water that normally strikes the eyes of a person peering into the aquarium.
