Just to get things started, I decided to put some paint inside the tank to see how it was going to look. I have much to do in there, but I couldn't resist seeing how my carefully painted rays of light that run diagonally across the waves would look with the LEDs. I think it's looking good.
Once I had these initial parts, I decided that I wanted him to be wider, with a much larger mouth. By adding a strip down the middle, I could get exactly what I wanted.
