You know what? I really wouldn't want this.
That front tank will be full, which means it'll be similar to the fluval edge with a raised section for air exchange, so it would have to be fairly lightly stocked. You'd use it to put drinks and things on, so no sensitive species that get stressed by taps on the glass. Maintenance would be a pain. Lighting it would be inefficient...
That said it's a bold statement piece.
