Abstract: A shipping wrapper for an aquarium, the aquarium having a bottom, a front wall, a rear wall, and end walls interconnected to form an enclosure, the front, rear and end walls having an overlapping rim on the top edges. The wrapper has a bottom panel, end wall panels, and end wall rim panels hingedly connected together along fold lines and positioned generally adjacent corresponding portions of the aquarium. End flaps are hingedly connected to the end wall rim panels, the end flaps each having outwardly extending end tabs with locking edges. The end flaps are folded into the aquarium so that the locking edges of the end tabs are captured beneath the overlapping rim on the top edges of the front and rear walls of the aquarium.
