Do fish sleep?

[Laura]

So, Saturday night I'm out having a few drinks. I come home rather late about 1am.

I take a look-si at the tank, and there are no fish to be seen. Mind you I have an Oscar, who is always there when you get home.

I take a closer look, and low and behold, I see the grouramis at the bottome of the tank, no fins moving or nothing.

Then I see the convict wedged between 2 rocks that hold up this cave thing I made in there...so now I start freakin' out, thinking he got spooked and stuck himself in there.

So, I turn the light on, and there is Oscar laying sideways in the middle of a plant, looking all dead...to make a long story short after about 5 mins with the light on the fish start waking up...

I never knew...do they actually sleep?

yep fish sleep on their sides or float around, unless someone proves me otherwise

the cute'st fish to watch sleep is rasboras hehe. When they sleep they stay in a school and you see their silver belly in the ambient light!

Yes, they sleep. When all the lights go off, they'll go towards the bottom of the tank or on a rock or wherever their favorite place is and their color usually fades, but when the light goes on, they wake up and regain their color. They don't have eyelids, so it looks like they're dead most of the time!

Both of my Sunburst Platys love to sleep on top of this fake cave. It's adorable. They slide down when they stop moving so they end up wedging themselves in a corner. ^_^

They sleep and lose their color. I awoke one morning and looked at my betta. I thought he was dead cuz his color was gone and he didn't appear to be breathing. He was just in a really deep sleep. LOL

Thats It!! all my fish fell asleep ! i thought they was looking pretty tired, even that crawdade thought they were dead when he was eating on them,, and all this time they were sleeping,, dang fish

Yep fish gots to sleep, although mine sort of idly float around and bump into things sometimes most of the time they wake up before that. Its kinda cute and funny to watch at the same time.

My goldfish sleep in a huddle in the corner and my female betta squeezes herself under a plant leaf, it looks like my fish are going retarded.

Mine all sleep inside structures, otherwise they get terrorised by the nocturnal pictus cat =)
