Do Red Eared Slider Turtles Sleep And WHEN?

All turtles sleep especially the RES.
They need sleep from 7-12 hours a day
so when you go to bed you turn all the lights off, they will sleep thinking it is night time
when you wake up you turn the lights on, they will slowly wake up thinking it is morning.

In the long run buy a timer so it automadically does it for you.
You will have to think what turtles would do in the wild and make their habitat as close to that as possible.

Well my RES he is only as big as a quarter and he was sleeping at the bottom of his tank I thought he was dead... It really scared me .... But when I went to pick him up he moved so I was happy ..then I hopped right on google and asked if RES sleep in and out of water..!!!! I love my RES!!!! :))

Yes,RES do sleep when there is not much noise around them and when it is dark they often sleep when they are basking do you have a basking place for your turtles if not you should make a place in the wild they basking in the sun any where from 8 to 10 hours a day.

Yes they do sleep and they usually sleep when it it quiet around him/her and feed him once in the morning and once at night =-))

Yes Res will sleeps at night, and can be awaken easily when someone enters the room, or near by him. If you have more than 1 res, they usually not sleep much, but they do rest underwater.

Yes, they do My r RES is sleeping right now on a rock

I bought a new RES but his still like one month only and he only sleeps and doesn't what to eat

Instead of a floating platform get a big solid rock.
Is the food to big?

I have a yellow-bellied slider, but they're in the same family so it's probably the same sleeping habits. I notice that mine sleeps in the water sometimes, either with his head underneath the water or he'll stand with his body against the side of the tank and sleep that way.
When he sleeps underwater he'll come up every so often for a breath but I think it's just done instinctively, I don't think he really wakes up.
Your turtle will probably just find a way that he's most comfortable sleeping and choose that, whether it's in the water or on land. =) I suggest  you Sleep cycle alarm clock through this you get more results about Sleep Cycle .

They sleep whenever they please, mine sometimes sleep underwater, or when they are basking. Charlie can sleep through a lot, Morgan on the other hand cannot he will wake up as soon as I enter the room.

The Red-eared Slider turtle refers to a semi-aquatic turtle that belongs to the family Emydidae. It is a native animal of the southern United States. They do sleep and their sleeping pattern is not determined or fixed. It depends on the habitat they live in.
