The idea of the headboard tank is awesome, but the execution of it seems weird. I think the arch in the top is the problem for me. Everything else is nice clean lines, then a crowded arch. Or maybe it's that the arch just seems too narrow. I'm not sure, but something bugs me. Of course, that could all just be because of the angle of the photo.
The living room tank needs to have the tvs taken off. How do you even see the fish in there unless you peer through the end? I have to wonder if this picture was taken before the tank stand and stuff was completely finished and that's why all of the electrical is exposed. If you look at the bottom of the tank, you can see all the plumbing, too.
