○♥Do fish sleep?♥○?

Answer 1

Yes, and with their eyes wide open!

Answer 2

Everyone needs sleep. Every night average people perform a sleep ritual: We change into pajamas, crawl into our soft comfy beds, close our eyes and enter into a restful state. Our hearts slow down, we breathe slowly and regularly, and our muscles become relaxed. Once or twice an hour we roll over, but we are no longer tuned in to our environment. We spend about 8 hours a day sleeping – that’s one third of our lives.

Sleep means different things to different forms of animal life. The Saunders Comprehensive Veterinary Dictionary sums it up pretty well: 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 in many species these daily cycles are similar to people running around during the day then lying down at night and doing nothing or sleeping. 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. Unfortunately, fish have no eyelids so it is difficult to tell whether they are asleep or not.

Answer 3

Yes, fish do sleep. That's why it is important to turn off the tank light at night. It helps the fish relax and sleep. They rest and conserve their energy by sitting on the bottom or gently resting on a plant. Once you turn on the light within a few seconds they start moving all around and wanting to be feed.

Answer 4

YEah of course they do. They sleep to conserve their energy just like humans do. They do not close their eyes when they sleep simply because they don't haven eyelids to close their eyes.

They conserve their energy when sleeping by staying still in the waters. But they are in a semi awake condition so as to sense and be on guard and alert for enemies. But thats only if you fish is in the open sea or place where there are predators. IF your fish is breed in your own aquarium, most probably, it would sleep more soundly.:)

One more thing, remember to off the lights shining on the tanks for the fish needs rest just like us!

-Hope the above helps.

Answer 5

Yes, they do. That is why it is important for the fish owner to turn off the lights in the tank at night. Fish have no eyelids, therefore they cannot simply close their eyes to sleep.

Answer 6

Some fish do for sure. I am a diver and I have witnessed sleeping fish many times. The answer is yes for some, but nort all species.

Answer 7

like all living animals, fish do sleep but with their eyes open as they do not have eye lids. remember to turn off you fish tank light every night to not only save energy but to let the fish sleep!!!!

Answer 8

Yes

Answer 9

fish go into a sleep state where only half of the brain goes to sleep but the other half of the brain is awake fish do not close there eyez when they sleep because they have to be alert for enemys.

Answer 10

Yes, they sleep with their eyes open. So when you see them in one spot for a while at night they are probably sleeping.

Answer 11

Yep! Mine lay on the bottom of the tank and sleep every night. They don't have eyelids though, so you'll never see them with their eyes closed! Make sure you turn off your aquarium light every night, as they won't sleep with the light on.
