do fish sleep?
and do i need to turn off the light in the tank at night?
I think they sleep or atleast rest. When I turn my light off at night in the morning when I come to turn the light on they are all very still and just floating usually at the bottom. Once the lights are on they are back to being active. I always turn my light off when I go to bed and when I wake up in the morning I first turn the ceiling light on and after a few mins i turn the tank light on so they have time to adjust to the light and not startle them. I think its a personal preference if you want it on 24/7 or not. If you keep it on constantly you will probably end up with algea problems. I think fish enjoy having time without a blaring light on all the time.
Thanks for the help!!!
yes they sleep and yes the light need to be turn off at night
yes they sleep but since they don't have eye lids we dont see them shutting off their eyes
Yes and they can sleep with the light on but it is best to turn the light off
you will know when they are asleep because they will be as stiff as a statue only moving gill covers and mouth to breath unless they dream of being chased by an Oscar or Piranha then they will dart aroung the tank alot
My Shubunkin Goldfish once had that happen and woke herself up by running into the glass
You should definitely turn light off at night, fish like a cycle similar to that of day. It will cause much less stress. And besides I would not want my bedroom light on 24/7. The easiest way is a timer, Walmart, brinks timer. $5.99. Not having to turn light on and off. Priceless.
i turn their lights off before i go to bed. i find it very interesting to watch my fish sleep. i think they appreciate having the lights off while they are sleeping.
On our planet we have day and night and all animals evolved around this feature and have internal body clocks. Some fish are diurnal and some are nocturnal (if you're nor familiar with those words,please go to MAC Complete Glossary where you can find explanations). Fish sleep but their sleep is more like 'trance' than a sleep as we know it. They rest, have metabolism slowed down but their brains do show the same REM phases as mammals including humans have. Some fish like sharks are thought to have continuously swim during the resting period. and parrot fish secrete a sleeping cocoon that helps hide from predators.
That is what I was implying
Yes they do. And no you don't need the light off for them to.
It's nice for them to have a day and night cycle. I suggest you buy a light timer. It's easy to forget. Typically you'd want the night cycle to at least be 10 hrs. With 14 hours light. It's your preference but since they don't have eye lids so they need to have no light.
I try to keep my light on at a minimum of about 8 hours a day .. I'm a night person so I tend to turn the light on at night mostly .. And yess they sleep, not like us humans do.. they go into a trance .. there always moving there fins and breathing probably slows down a bit ..but they appear to be kind of frozen looking, just floating in one spot .. it's kind of neat, like they are sadated.. I can tell their asleep because otherwise they would run up to the glass to greet me... and somethimes they take awhile to wake up .. it's so funny.. you just have to observe their behavior .. here's a link I found
OF COURSE FISH SLEEP. HOW ELSE WOULD THEY GENERATE ENERGY TO SWIM AROUND AND PLAY TAG ALL DAY.
55 GALLON TANK:
10 GOLD FISH
3 BALA SHARKS
6 ALGEA EATERS
1 RED-EARED SLYDER
1 YELLOW-EARED SLYDER
no that is stupid
thanks for help
YES, fish do need down time to relax without a light on.
My cat fish, Molly and guppies, all sleep for at least 8 to
10 hours. It's important to allow them to adjust to
natural light before the tank light gets turned on as they
do get startled. Open the curtains or turn on the room
light for a few minutes first.
Dragging this topic from the depths...
I've had my aquarium for a week and I think I've left the dark blue led light on the hood on every night. Could cause a problem with the fish rest cycle or should it be as dark as naturally possible?
I wouldn't have any light on whatsoever. I make sure all of my lights are off. Not only do the fish need rest, but if you have live plants, they need rest too and will not get it if you have any lights on.
Like mammals, fish have circadian rhythms. When I forget to turn off the lights in the evening, it doesn't seem to affect their sleep cycle. On the other hand, a sudden transition from darkness to bright lights will sometimes send the fish into a panic. I usually turn on a room a half hour or so before turning on the aquarium lights.
My shark's name is Oscar!
That's a lot to many fish for your tank isn't it ??
Yes it should be dark completely for them
They definitely have a sleep cycle
When my guppy fry and angelfish fry (separate tanks) go into sleep cycles, they always return to the same part of the tank and sleep in a big group, sometimes with one little fish that still occasionally roams the tank every once in awhile. If I turn on my lights too early, some of my fish actually go into shock. One of my adults will completely flip over and float upside down for awhile before he recovers
Long story short, yes they do, and you should work to provide good conditions for your fishes sleeping habits, e.g. places to sleep like plants and caves for some species, as well as partial lighting from a decoration or tank lid specifically designed with a "night time mode."
Hi, fish do sleep but you can't see any closed eyes only you can see they kind of float about and do turn the light off at night. Some fish like 12 hours of the light on and 12 hours of the light off hope that helps!!!!😉😉😉
I knew that too but good job being smart.lol my Kim k game!
thanks because i have four fish and i was curious if they sleep or not
It's so funny when you knock the lights on the bettas are like me on a morning dazed half asleep and clumsy but as soon as I knock the room light on the guppies dart all over the place(like my sister 😂) the bettas just swim into the glass😂😂😂😂😂
