Yes fish sleep. Watch Goldfish and you will see them sleep..Heard one of mine snoreing the other day. Just kidding..

I've always wondered this myself, i not sure they do, if so how can they sleep?

i found this on a website.They were asking the same question do fish sleep and this was the answer:

It all depends on what you mean by sleep. My dictionary says that sleep is a period of rest in which the eyes are closed and there is little or no thought or movement. That is, sleeping means closing your eyes and resting. The first thing we notice is that most fish don't have eyelids (except for sharks). Also, while some deep ocean fish never stop moving a great many fishes live nearly motionless lives and many do so on a regular diurnal/noctural cycle, some active by day others by night.. So we can't generalize and say that all fish sleep like we do. But most fish do rest. Usually they just blank their minds and do what we might call daydreaming. Some float in place, some wedge themselves into a spot in the mud or the coral, some even build themselves a nest. They will still be alert for danger, but they will also be "sleeping."

OMG someone must put this question up at least everyday!!

no they just rest

All living things, even plants, have rest periods.

fishes hibernate, it is kind of sleep and it can take some time for them to wake up.
