A wall mounted aquarium, is constructed from a structural material frame and a glass aquarium mounted within the frame. Preferably, the structural material is a metal that can be welded, such as steel. Structural polymeric materials and composites now known and hereafter developed, can be used. The structural material frame has a front side and a rear side. Preferably, it is formed from a pair of vertically oriented "U" shaped channel members. A horizontal "U" shaped channel member and the pair of vertical "U" shaped channel members are bonded together to form a "U" shaped frame unit. The "U" shaped channel members open inwardly. A glass aquarium having five sides and an open top end is mounted within the frame. One of the sides is a front side, one of the sides is a bottom side, one of the sides is a rear side and two of the sides are ends. The channel members can be tubular or have an open "U" configuration.
