Got a 44 hex tank in the bedroom. For years it was in the den. It was actually my wife's idea to put it in the bedroom. Got led moonlights on a timer that are on at night and on in the morning serving sort of as a night light. It's great. Highly recommended.
I run the lights in the 55g in my bedroom from about 3pm-12am. Most of the time I am in bed before they go out. If not, I usually have a side lamp on when the light goes out so it doesn't go totally dark in my room.
