In "MonstaFish" mode your aim is to remove your job is to clear the water of mutant fish (MonstaFish). An octopus blow bubbles, which you guide together using your finger, and then burst next to the toxic fish to deflate them. In "Fish Hunt" mode you have to be as accurate as a sharpshooter with finger taps to hit the fish.
In "Time Attack" mode you remove as many fish as you can, by tapping on them, in three minutes. In "Fish Hook", using tilt controls, you guide a hook to the bottom of the screen to rescue goldfish and then pull then back up to the top of the screen, making sure to avoid the shoals of MonstaFish along the way.
There's also a "Fish Tank" mode, which is really a showcase for the different type of fish in the game.
