Create a custom function (like drawFish) that draws a fish. You can build on the starter code or start from scratch.
Add at least 2 parameters to the function declaration that control either the position or the size of the fish.
Now call that function many times, with different values as arguments, so that your screen is filled with fish.
Bonus: Add more parameters to the function declaration, like color, tail width, eye size, tail color—more ways that you can make each fish different from each other.
Bonus: Add seaweed to the tank, pebbles at the bottom, or bubbles floating to the top. Whatever objects you add, make a function to draw them at different places.
Bonus: Want to make it interactive? Use a mouseClicked function to add more fish wherever the user clicks.
