actually a lot of people recommend feeding some fish after lights out if you've got aggressive fish in the tank to make sure everybody gets to eat. so i don't think that that would be a problem.

if there is enough natural light in the room where the tank is then IMO it shouldnt be too much of a problem. i know some people that have lots of natural light only turn the tank lights on when it starts getting dark

It's a pretty dim house, especially in the winter (all my houseplants have gone to my office bc I couldn't keep them alive at home, even right by a window). It faces south (fabulous for petunias in the summer) but there's a stairwell/balcony in front of the living room window so the inside's a little dark. So no light during day = fishies in dark all day = two very short days/24 hours for my fishies, doesn't seem healthy to me either.

No aggressive fish (well my DG likes to boss the cherry barbs around). They all know their routine pretty well. When I turn the light on in the morning it takes a good five minutes for everyone to wake up

hmmm....yeah i'm not sure. it's probably not a big deal to leave it on longer then. i leave my lights on for closer to 14 hours depending on my class/work/other stuff schedule.

Lol, yeah but they should still be able to find the food and eat in the dark.
