Shells are the main income (and expense) of your very own Virtual Aquarium.

Collecting Shells

Shells can be redeemed in four ways:

1.Adventure Bonus Rounds giving about 1000 for the first tank and about 2500 for tank 4 if you use chains (Gives 80x the base value if you collect 10 in a row for the same increment)

2.Time Trial which converts 5% of your money into shells.

3. Challenge mode attempts (2000 for tank 1 and 5000, 10000, and 20000 for tank 2, 3, and 4)

4. Dropped by Virtual Aquarium Fish. They drop grey, gold, and blue shells for medium, large, and king guppies.
