Your fish really don't like the light on all the time. Think of their natural environment when the sun goes down. I always leave the lights on from when I wake up until when I go to bed. If you leave the light on 24/7 is causes algae to grow out of control. But having it on for about 10-12 hours a day is good, plus you do want some algae that is actually good for your fish.
Don't worry about how they sleep, they get their rest whenever they need it, light or not(depending on the species).

If you have the light on 24/7 the tank will probably become overgrown with alga. Fish need the simulation of day and night to remain healthy., Fish become less active at night. With constant light the fish will consume more energy and will not easily breed.

It is best to give the fish some time with the lights off. In nature fish would have day and night just like us.

Yeah fish do sleep so it is a good idea to turn off the lights especially if you dont have a hiding place for them . your only suppsed to leave it on for 8 hours but some fish like natural light(sunlight) because the light is too bright besides leaving it on for so long is a waste of electricity. I heard when you turn off the lights the fish's colors actually turn pale if they're colorful

According to the company that maintains our tank in the office, too much light (artificial or sun) causes algae blooms.
I would imagine fresh water fish can sleep whenever they want :]) but even in the 'wild' there are cycles of light and dark - you want to try to replicate that as much as possible for your fishes' well-being.

Yes that is bad..
Fish need a normalized day/night schedule just like you do. Why would you ever want to leave that light running all the time?!

YEAH ITS BAD. FISH NEED LIGHT PERIODS JUST LIKE WE DO. TRY TO GIVE THEM 10-12 HOURS OF LIGHT AND TURN THE LIGHT OFF AT NIGHT. IF YOU DON'T IT MESSES UP THERE SLEEP, EATING, AND BREEDING PATTERNS. THIS WILL CAUSE STRESS IN THE FISH WHICH COULD LEAD TO DEATH.

They dont have eyelids, meaning that they can't blink or even close their eyes. But it is bad because the chance of eletrical shock is increased for you and energy bills may go up. They do however go into a resting stae I hope and they might cna sdense the change between day and night
