Can fish sleep with the lights on?

Hi All,
I recently set up a new SA community in a 4ft tank in my home office. The problem is my girlfriend and I both work nights and we tend to be up at all hours doing work with the lights on.

I've noticed that even when I turn the tank light off, all the fish stay awake and won't go into 'sleep mode'. The room gets light early as well, and even thought the tank isn't in the sunlight it still gets lit.

Are my poor fishies going to suffer from sleep deprivation? :-?
should I cover the tank at night?
Am I just being weird? :oops:

Cheers,
Mcflyyy

Thanks for your advice, most fish like my rams etc have no trouble but the ever-curios severum has been up till all hours watching us. I might raid the sheets cupboard...
