College, ah those were the days! 8)
, it won't do much good to turn tank lights off if you are in the same room with other lights on, partying and whatnot.
Anyway, they do need some dark time, can you close the curtains in the daytime? Even if not full dark, they can catch some zzz's. I think if you can do that your fish will be happier. Do your roomies work late too, or all on differing schedules?
I guess my conclusion would be try for 6-8 hours of dark/semi-dark, quiet room. That may be impossible, but thats my best guess.
