Abstract

Abstract An aquarium in which usually all of the walls are made of glass. Usually the back of the bottom is usually horizontal and the front portion of the bottom (or a part of the front portion of the bottom) is inclined upwardly at an angle of 10* to 40* and the whole of the bottom may be so inclined. In either case, the front of the bottom will be transparent and lighted from below. The back portion will be covered with sand or the like. The front of the bottom is transparent and lighted from underneath. The lighting fixture is hidden from view. As an alternative, both the front and back portions of the bottom may be slanted upward, and the middle of the bottom which comprises parts of both of the slanted portions or a separate flat piece, will be covered with sand or the like. In this case the bottoms of both the front and back walls are made opaque to hide the light source from view. The rest of this disclosure will describe only those aquariums in which only the front portion of the bottom is inclined upward and lighted from below.
