Maybe Jim could come up with an add-on pack for the Freshwater Aquarium. It could be called "Your Childhood Aquarium," and could include Guppies, Swordtails, Mollies, common Goldfish, a diver that sends up bubbles, your choice of a number of neon-colored gravels for the bottom of the tank, and various colored "crackle-glass" effects for the background. This pretty much describes my first aquarium, except I also had a ceramic castle that the fish could swim through.
