Draw a Fish Tank

Fish tanks are really fun and easy to draw. They use only basic shapes, and will take only a few minutes of your time. Let's begin!

Steps

Draw a rectangle and two horizontal lines inside it, one on top and the other at the bottom.
Draw small pebbles on the bottom, use curved lines and a few circles.
Sketch a large corals inside your fish tank.
Add a few seaweeds. You can use short curved strokes.
Draw fish, they can be of different sizes. You can also add starfish and shells.
Refine the details of your drawing. You can add a little texture to the stones and corals by adding a few dots.
Color your drawing.

Draw a simple rectangle about 2x4 inches. Make the top bold, to show that that part is the lid.
Draw the outline of the filter. Make lines so that it looks 3-D. Now add the water line.
For the pebbles at the bottom, simply make a series of circles. The little seaweed plants are easy too, just make it like a mini tree. First the trunk, then two or three main branches, then a few sprouting from them, and a few sprouting from them until it looks full enough.
Here's how it should look finished. Enjoy your fish tank!
