Do fish sleep?

[Cats Critters]

My little sister came in my room and watched me on here for a little bit and then turned around and started watching my goldfish, her Question to me was do fish sleep? I think no and she thinks yes who is right?

i dont know if they sleep but i do know they 'rest'

Yes. My clown fish puts his self in some algae after dark an sleeps most of the night.

Of course they do. They also blink, but nobody believes that bit until they actually see it for themselves (their eyeballs turn down into their heads).

Somebody should write a book "Everybody Sleeps" lol!

It's not really "sleep" but they do have to shutdown their brains for a rest. That's when they are not alert and get eaten so they hide them selves in a crack, sand, or weeds.

Thanks! I have had fish for years and had never thought about it before, I think he is "sleeping" right now he just kind of flouting there not moving much besides so small fin movements.

She is correct -- fish do indeed sleep. Parrot fish even go so far as to create a sleeping bag of sorts (a mucous-y layer that helps protect them from predators). every night before bed.
