Having it on a regular schedule is best, the fish's metabolism is in sync then. Just like humans; I heard on the news only this week that people who work shift work have more trouble with the 12 midnight to 8 am shift, simply because of our internal "clock." Fish have these things too.

Another point, when the tank light comes on and when it goes out, there must always be some light in the room so it is not a sudden light/dark situation.
Really? :S Mine sometimes go off completely in darkness or on (one fish tank is in the laundry room which is completely dark). What is the best way to adjust the fish to going from light to dark in this case? =s A light on in the room? Wouldn't turning that off shock them too though?

The sudden shock of the tank light coming on or going off in near-total darkness can stress fish very much. What I do is have the lights come on in the morning when the room has daylight [they come on at 10 am not just for this but because I like them on during the evening and have to keep it to 11 hours, so 10am to 9pm]. In the evening I have a lamp in the room that is also on a timer, it comes on about 5 minutes before the tank lights go out, so when they do, the room is lit with the lamp. It is positioned such that it casts a bit of light onto all the tanks.

Once or twice the timer on the lamp has not worked, and I have been sitting there watching the fish when the tank light went out in darkness; the fish immediately went into a frenzy, I heard several bash into the glass top, and saw them scurrying around frantically. When the tank light goes out with the lamp on, they do not do this; yes, they will swim toward the lamp light, but not with frenzy and no crashing about. The lamp itself goes out about 30 minutes later, and there is no reaction to this; by then they are prepared for night.

You would think that over time fish would become "used" to tank lights on and off. But obviously nature has programmed them to "expect" dawn and dusk, and that stays with them in the aquarium.

Something we all need to remember: The fish you've acquired was quite happy not being owned by you, minding its own business. If you’re going to take it under your wing then you’re responsible for it. Every aspect of its life is under your control, from water quality and temperature to swimming space. [Nathan Hill in PFK]
