I had a 77 in my bedroom years ago. I had several other tanks in the house and the bedroom tank always seemed to be the one that got neglected. Other than sleeping, I was really never in the room to enjoy it. I ended up selling it. I like my tank in the living room, where it is the center of attraction and it's where I spend most of my time. There were moisture issues. Used to get mildew on the ceiling where it met the outside walls. Of course, I live in Louisiana where it is always too humid anyway.
