When fish sleep at night...

[Mr31415]

...do they ever stop swimming? A stupid question but bugging me nonetheless.

[dime079]

probly, i catch my gramma chilling (resting) on the rocks not waving any of his fins, all the time :)

[jprince58]

I thought my son was trying to pull a fast one on me when he said our long-nose butterfly slept on its side at the top of the tank...then I saw it. All the other fish find themselves a nook in the rocks, but not this one. There it was, completely horizontal and just sort of floating on the surface. Oddest thing I'd ever seen!

[Paintbug]

each type of fish is different. my clowns will often make a bed in the sand and lie on their sides at night. my powder blue tang rarely stops swimming. i had a stripped fanged blenny that would sleep in the corners of the tank, like hes stuck on the silicon sealant. he would even sleep on the bottom of the mag float. some wrasses will make a cacoon each night. so you will see many strange things when the lights go out.

[Octoberfest]

when i tell people that my fish sleep they think i'm nuts. the girl I'm dating asked me why my yellow tang looked pale one day and i said it's because i woke him up early, he's use to sleeping in later and she thought i needed help.

Saltwater fish are weird....

My wife and I got into this about 8 months ago. Now I have $150 dollars worth of fish that never swim. Weirdest thing. Clowns chill in the anemone, triggers chill in the rock. Come out to eat and see the kids every once in a while....

My percula digs a hole in the corner and sleeps in it's side at night. It scared me the first couple of times he did it, I thought he was dead. It's totally normal though.

[NCreefwannabe]

yeah my clarkiis slept on the rocks every night about 2 inches apart on their sides and looked deathly pale lol. I freaked too.

Does this mean that my clowns never get any sleep because I have an emerald crab that goes hunting at night, and a snowflake eel that is also nocturnal in the same tank. Now I get the feeling that my clowns sleep with one eye open.

I guess fish sleep with both eyes open as they dont have eyelids :confused:

[doox00]

my 2 true percs never stop swimming, when the lights go out they go next to the overflow and kinda do a slow wiggle swim, they never go into the rock either in the tank, they swim around a little bit through out the tank but never into the rock or on the bottom for some reason.

[Crusty Old Shellback]

I had some large tangs that would go to bed together in the back of the tank between the rocks. It was weird seeing 3 large tangs of different species all laying on each other like they were stacked up against the back.

My blue tang and pink tail trigger both lock theirselves in the rockwork to sleep.

[efroggies]

my false perc goes up to the top of the tank near a pump out of the flow and just wiggles all night

[roadrunner1659]

my percula clowns go up into the back left corner of my tank and they hover together facing straight downward...sometimes one switches it's direction to they are face to face...i my lemonpeel wedges himself inbetween rocks or the rocks and glass and he stops moving at night time...and i dont know what my sixline does?

[Sk8r]

My mandarin has a fave spot right up against the curved front of the tank: never varies. Must be just the right flow in that area.

[theop]

The sixline wrasse will pick a "spot" in your LR and always go there. They secrete a mucus cocoon to sleep in.

I have the same problem, my only swimmers are my clowns.

On a side note I have seen my african cichlids "sleep" laying down on the sand @ night

[Leandrae]

My clowns snuggle up in their anemone at night to sleep. The 2 royal grammas are no where to be found at night, so I assume they find a nice spot in the rock. My jawfish stays in whatever his current dug out is that night. My mandarin has a place on the sand and looks for all the world dead...scared the bajeebers out of me first time I saw her do that.

[Infern0]

My clowns also float at the very top of the tank...I'm suprised they don't suffocate by morning, because they have half their body out of the water.

[Marinemom]

My clown goes behind the same rock every night to sleep. My tang goes behind a rock on the other side of the reef and my sixline wrasse digs a whole behind a rock every night and sleeps there. Once I turned the lights on a little early and my yellow tang had white streaks on the sides of his body. Within minutes they were gone. Sure freaked me out. The saltwater adventure is sure an eye opener.

[Fmellish]

My blue tang and my anthias sleep upside down in a crevice in the ceiling of their cave.

My 2 clowns never stop moving. Even at night in the anemone, they still wigggle while they sleep.

My six-line wrasee sleeps in a mucus cocoon he creates in a hole in a rock.

My Pajama cardinals stay afloat out in the open. They neve go into the rocks.

My sailfin tang sleeps inside a cave, (rightside up though).

My dwarf angel sleeps in my rocks.

Exactly what my Ocellaris does. Goes into the back left corner above my powerhead and just kinda wiggles facing the glass all night.

My yellow tail damsel on the other hand goes into a hole in the LR and sleeps in one spot.

[NCreefwannabe]

guess i had weird clowns then.....

My remaining perc does exactly the same!
