You start out with 3 fish. The fish will get bigger overtime. When the fish get big enough, they will make more of themselves, and eventually, die. Click on the fish to sell them. Click "Buy a fish" to get another for 100 FishCoins. Carnivore fish cost 150 FishCoins, but they do not grow overtime. The only way for them to get bigger is to KILL THE OTHER FISH! This gives you more money than if you just sell the fish. Rainbow fish cost 400 FishCoins, but they are worth the price; The sell for 3 times as mush as regular fish, and they multiply really fast!
