In a process for the dual use of packaging for a fish-related product such as fish food or a fish-related consumable product normally dispensed into an aquarium, a package including a compartment is filled with the fish-related product which is then dispensed until depleted. The dual use package is then placed within the aquarium and utilized as a decorative ornament. In this regard, the dual use package may be reconfigured for use as a decorative feature within the aquarium, and ballast may be added to the ornamental container before being submerged.
