Sleep means different things to different forms of animal life, however, sleep is defined as "a period of rest during which volition and consciousness are in partial or complete abeyance and the bodily functions partially suspended; a behavioral state marked by characteristic immobile posture and diminished, but readily reversible sensitivity to external stimuli." Most animals have some daily pattern of rest and activity and these daily cycles are similar to humans who are active during the day then rest or sleep at night. It is believed that fish are no different, although it is a controversial subject. Some fish keep very still, experiencing a quiet period (quiescence) that you might call sleep. Scuba divers often handle reef fish in the middle of the night without startling them and can even lift some species out of the water before they "awaken." Tropical freshwater fish in home aquaria appear to be resting immediately after turning the lights on in a room that has been darkened for several hours. So, if you define "sleep" in this term, yes, fish do sleep. Diurnal fish (fish who are active during the day) sleep at night and nocturnal fish (fish who are active at night) sleep during the day. Unfortunately, fish have no eyelids, so absent this obviously slowed movement or reaction time, it is difficult to tell whether they are asleep or not. And, as fish do not have eyelids, no, they don't even close their eyes if they die.

Fish don't have eyelids, they never close their eyes. Fish are sleeping if they are just hovering there not moving much. Some may lay on the bottem to sleep, but those fish may be sick.

Fish don't sleep.It's a survival thing. They just relax but never sleep. They would die if they did. So if you ever see a fish sleeping you'd be the first in the world. Or there dead.

You can't see it sleeping because it sleeps with it's eyes open. It usually hides away from people because they are distrubing. So, when your fish is hiding it's only hiding from all distrubances around it. That means, don't try to make it come out. Just like a person =] Hope this helps.

They tuck themselves in with a nice warm milky cup of Horlicks and read a book for a while. When asked the female fish says "I've got a head-ache" and then they turn out the lights.
