Nice tank, what you putting in it? Are you worried that you will see through the tank into your fish room and that would make it look less nice? (i.e. seeinging into the fish room from living area might not look so good.) or do you have some sort of background of somthing else to block from seeing right through the tank?
Also you designed your living room facing in the wrong direction, the couches seem to be facing away from the tank, but I am sure that is just a mistake....
