Fish Tank looks nearly real!

I bought lights nd Fish Tank as a present for my son. He has now built and assembled everything and, when lights are on, the fish tank looks nearly real. It's fantastic!!

Lights are of great quality. Instructions were fairly easy to read and follow. Really satisfied with the final lighting of the fish tank.
