The Fish Emporium sells many different kinds of fish for the Virtual Tank, but it also sells upgrades. Upgrades are found in the bottom-right store slot and must be purchased in order as there are only one of each.
Bubbulator[]
The Bubbulator allows players house up to 20 fish at once. It costs 20,000 shells.
Alien Attractor[]

Food Upgrade[]
The food upgrade changes the flake food for guppies to vitamin-rich capsules. Fish need to be fed less often and they grow faster. It costs 20,000 shells for a cumulative cost 90,000 shells.

Cookie is a pre-named beetlemuncher that will feed fish with more exotic or special diets. It eats guppy food instead of beetles. Cookie costs 50,000 shells for a cumulative cost 140,000 shells.
