Defining the fish

In Angry Fish, we have five different kinds of fish. Since they will share a lot of common behavior, we will define a base Fish class and inherit from Fish to specialize the behavior wherever required.

The following table describes each fish in brief:

Type of fish	Class	Description
Simple	Fish	The simplest kind of fish that can be launched from the catapult
Shooting	ShootingFish	Once launched, tapping the screen boosts this fish's velocity in the direction of motion
Splitting	SplittingFish	Once launched, tapping the screen causes this fish to split into multiple smaller fish
Bombing	BombingFish	Once launched, tapping the screen causes this fish to hurl a smaller fish downwards
Exploding	ExplodingFish	Once launched, this fish automatically explodes after landing or hitting something
