They can fall into a semi dormant state, but they must keep minimal movement to some degree in order to keep water flowing through their gills.

Hey there,
Most fish spend part of every day asleep. Being asleep can mean different things to different fish.
Some fish (like herring and tuna) are motionless in the water during the night. Other fish, like rockfish and grouper, don't appear to sleep at all.
They rest against rocks, bracing themselves with their fins. Also, some freshwater fish (like catfish) swim up under a log or river bank for shelter during the day.
Also, fish do not have eyelids, thus can not close their eyes while they sleep - that's why you might be asking this question.

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. Many fish, like Bass and perch, rest on or under logs at
night. Coral reef fish active in the day, hide and rest in crevices
and cracks in the reef to avoid being eaten at night.
The resting behavior of fish is very different from their behavior the
rest of the day. Many minnows, for example, which are very active in
schools during the day, scatter and remain motionless in shallow
water at night. Many fish "rest" or "sleep" during the day and are
active at night instead, but almost all fish sleep.
There are some animals that never stop swimming, like many species of
shark, however, they HAVE to keep moving to push water through their mouths
in order to breathe, and they may still sleep while moving,
we just don't know yet

Yes, they do sleep, but not as humans.
Usually they sleep with open eyes.
