Sand Dollars in FishVille
When you're first setting up your tank, you'll notice that you have the ability to accumulate both coins and Sand Dollars in FishVille. However, once you really start to play the game – buying and selling your fish and decking out your tank – you're really only dealing in coins. And that's a good thing too, because Sand Dollars are much harder to come by in the FishVille world than coins are. Because these Sand Dollars are so difficult to accumulate, it's important that you save them and spend them only when you have no other choice. But how do you know when that is?
Beware Frivolous Spending
There are a couple of ways you can spend your hard earned Sand Dollars in FishVille. One way is to purchase certain specialty decorations and plants from the store. While these decorations may be tempting, and will certainly award you a lot of experience points, they're not worth spending your Sand Dollars on unless you've managed to build up a substantial stash.
Expansion
The other main way to spend your Sand Dollars is to purchase additional tanks (when you don't have enough neighbors to do this with coins alone). While you could certainly save that valuable currency by simply sending out a few extra neighbor invitations, if you have the Sand Dollars to spend in a situation like this, it's not a bad deal.
Not Fast Enough
Unfortunately, unless you're willing to supplement your income of Sand Dollars in FishVille, you won't be able to rack them up fast enough to make them a truly viable option for sustained expansion. The most you can realistically hope for if you're trying to expand by relying on Sand Dollars alone is one extra tank. That's because you'll only be awarded one Sand Dollar in FishVille each time you move up a level (and not even at every level).
A Bit of Both
Really, the best strategy for using Sand Dollars to your greatest advantage in FishVille is to save them up until you have enough to buy an extra tank before you unlock it by leveling up. This won't be your first extra tank – you should still make sure you have enough neighbors to make your initial expansion move at level 10. But by saving up your Sand Dollars, you'll be able to get that third tank well before you unlock it with neighbors at level 20. By making use of both Sand Dollars and neighbors, then, you can maximize your ability to increase your FishVille business and advance quickly in the game.
