Most all fish spend time in an energy-saving state that can be called
"rest", and we might even call their behavior "sleep", though it is probably
different than "sleep" in most land
animals.

Yes, they just don't have eyelids to shut. They'll even have nightmares. (One fish will be resting at the bottom of the tank, then, all of a sudden, dart across the tank or hit the tank lid, and swim there breathing heavily.)
Maybe it dreamed it was being chased by a shark.
