I think the tank will look nice there, but I don't envy having to service, maintain, aquascape, move things inside the tank and access it in that position and in such close proximity to nice furniture. I know you can move the sofa, but IMO that would be an added chore I wouldn't want. That said, you will obviously not only need the ability to raise the light out of the way for all of the aforementioned, but it will need adjustability. I also think, like me, you'll want to conceal the wiring to preserve the nice look of your room and have a "finished" product. Maybe you can fabricate something similar to what I have for this. My light fixture and enclosure isn't very heavy so one stantion worked well. I'm sure you could used wood for this. Just need to be a little inventive. Keep us posted.
