yes

---

yeah

---

idk, good question

---

I think some do, and others just conserve energy.

---

yes, they do.

---

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.

---

fish have to keep moving to circulate water through their gill to breathe,

---

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.

---

yes. they stay in one place and are quiet. ( not swimming around. ) usually when the lights are off.

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.

---

maybe..yes.ok i don't know.

---

mine float around the bottom of thee tank with their eye open

---

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.

---

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

---

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.

---

yes,they all settle to the bottom of the tank in their favorite places at night and rest till you turn on the tank light the next morning to feed them.

---

Yes

---

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.
