Summary: Fish do rest but their "sleep" is different than land animals. Although most fish "sleep", some are still under speculation because some animals need to move to survive, similarly to a shark.
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.
