Possible dumb water change question...

Ok so I've never really thought about this but...
I've noticed that during the summer my water changes seem to be somewhat neglected because my weekend when u have free time during the day are so busy. But during the week after work I have all kinds of time. I work late hours and my lights are all on timers because of that...

So the question is: is there any reason I can't do a water change with the tank "dark"? Other than the obvious of me not being able to see as well, and the fish being in their "sleep" state and not being as aware so I'd have to watch out for sucking up fish.
I just can't really think of any reason why I shouldn't... Am I missing anything?

That's the only thing really that had me wondering, if it would spook or stress the fish too much.

The main tank I'd be changing in the dark has a finer sand substrate so I have to be more gentle and controlled pouring the water in anyway.
