With Fish Tycoon, you have to grow and breed fish until you have created seven rare types of fish to complete your collection. You are given a home tank and a breeding tank. Within your main Fish Tycoon tank, you are charged with caring for your fish. As they grow, you may breed them or sell them in your shop. Sell them to earn money so that you may better care for your fish by buying fancy food and medicine to heal your sick fish. Cross breed your fish and buy new fish to mix up your gene pool. The graphics are truly awful, but the game is fun for tycoon fans. It is similar to plant tycoon, but Fish Tycoon has more action than plant tycoon.
