Draw a Tropical Fish - How to Draw a Cartoon Tropical Fish

Here's a picture of the tropical fish I'm drawing. I think I based the original one on a type of Angelfish. Though it doesn't really look like one! But since this is just for fun, it doesn't matter. Now to start with I look for some basic shapes. It's got a square body, so I draw that, with a droopy triangle face, and then two more overlapping triangles make the fish's tail.
