From the developer:
There are many big fish, little fish and a pet fish in the water. Use your mouse to navigate your pet fish up, down, left and right. Eat as much fish that are smaller than you as you can but avoid getting eaten by bigger fish. Grow your pet fish to a bigger fish by eating enough small fishes.
