Many species of fish have periods where they are active and periods where they are not. That could be considered sleep; however, fish do not close their eyes because they have no eyelids. As well, some fish (like tuna and shark) rely on water moving constantly through their mouths to breathe, so inactivity is not an option for them.

Yes, they just do it with opened eyes cos they don't have eyelids.
They kinda swim slowly in place, and their reaction is very slow...
If you have an aquarium you may see your fish sleeping some hours after you put the lights off in the evening/night, or early in the morning before you put the lights on.

Yes they do it just does not look like it, because they dream and swim and rest at the same time.
