“Staying alive” even when the Nintendo DS is off, Fish Tycoon is a fish-breeding simulation that lets players raise fish in real-time virtual aquariums and crossbreed them to their liking to create new breeds to sell in their store. Selling fish provides funding for supplies, medicine, special chemicals, technology research and store advertising to attract more customers. Players start with a small selection of fish that they must nurture and breed as they work to discover the correct genetic combination for the “7 Magic Fish.”

• Special DS-only features: 7 exclusive fish yield nearly twice as many fish types as the PC version (over 750!); all new 3D environments and several new tank decorations;
• Extensive use of the Touch Screen to breed fish, make purchases and decorate tanks;
• Simulated real-time experience yields potential surprises every time you turn the game on. Choose from 4 speed options to dictate how time passes in game. Take regular care of your fish or watch your hard work get flushed down the drain!
• Set your own prices for specific fish based on prior sales and present needs;
• Buy fish tanks, decorations, plants, fish eggs, fish food, and medicine to enhance the aesthetic of your tank;
• Research environment, food, and advertising techniques to discover how to keep your rare fish healthy, feed more fish per feeding and attract additional customers.
