There are 6 000 000 000 people on this planet. Don't you worry: whatever it is you'll chose to do, you won't be the only one.
I have a 55g in my bedroom with discus. It hardly makes any sound at all. Sometimes I watch before falling asleep, but mostly when I wake up.
When an occasional Sinspilum jumps out of his tank in the living room, some 50 feet away, I wake up. That's why they are all still alive.
