Yea it's not a sure thing, but what turning the lights off
does, is it sends a signal to the other fish that it's
time to sleep.

I disagree with those expressing preference to do it with the lights out.
Just imagine yourself thrown in a dark room full of enemies. Where
are you going to hide? can't see!

I once had a powder blue that was very territorial. I added a fish once
with the lights out, but you could see the tang chasing it all over the
place. I think they may be able to see a good deal better in limited
light than we can. For that matter, the chasee seemed to be able to see
pretty well too!

Of course, that tang would chase a new addition with the lights on, so I
think it doesn't make any real difference.
