Should turtles be in water all the time?
They require a habitat with plenty of clean water for swimming as well as dry land where they can rest, hide and bask in the sun. A tank that can hold at least 40 gallons should give your pet turtle an adequate amount of room to move around in.
Although turtles are aquatic reptiles, they cannot breathe underwater in the same way fish can. Instead, turtles need to surface in order to take in oxygen while swimming, Hess said. “[Turtles] do need to breathe outside of the water,” she said.
Turtles will usually go into the water to take a dip or swim when their body temperature goes beyond 105 degrees, so you may want to check your basking temperature just to be safe.
Generally speaking, a turtle can go about 8 hours without water in a warm and dry environment. In this article, we will discuss which aquatic turtle species make the best pets, why turtles need water, and how to provide fresh and clean water to your turtles.
Sometimes people confuse turtles with tortoises. And they think like tortoises, turtles love to be out of water. But that is not the fact for turtles. They prefer being in the water and their survival becomes questionable when they are out of water for several days.
Most turtles are semiaquatic, meaning they divide their time between water and land. So your aquarium or other turtle habitat needs water and a dry area.
Turtle Sleep
Aquatic turtles may spend hours sleeping on a dry dock or with their head poking out of the water but they may also sleep underwater for shorter periods of time, coming up to take a breath when necessary. Land turtles don't swim like aquatic turtles so they can sleep anytime, anywhere.
Although turtles can hold their breath for 45 minutes to one hour during routine activity, they normally dive for 4-5 minutes and surfaces to breathe for a few seconds in between dives.
Yes, many turtles can sleep underwater but there are some species that can't do so. Aquatic turtles such as painted turtles, pond turtles, wood turtles, map turtles, and red-eared sliders can be found sleeping under the surface of the water. There are sea turtles that can sleep and live under the surface of the water.
If the water is much warmer than recommended or the ambient air temperature is too cool, the turtles will be unlikely to get out of the water to bask. Basking is essential for the turtle's health. It allows the turtle to completely dry out and warm up.
How do you know if a turtle is happy?
A happy turtle will show signs like begging for food, splashing the water, basking regularly, hunting and eating readily, being comfortable with handling, and being out and about.
Yes, turtles will get tired of swimming. They cannot be constantly left in the water without a basking platform or rock. Leaving them in a tank without access to a resting zone will ultimately lead to their drowning death.

When swimming, turtles with severe respiratory infections, such as those caused by vitamin A deficiency, can tilt to the side, causing them to flip over. A lack of vitamin A changes a turtle's mucous membranes in their eyes, mouth, and respiratory tract.
At least once a week: Replace some of the water in the tank with clean water. Even if your turtles' swimming water looks fine, it could be high in ammonia or nitrite. Every two to three weeks: Clean out the whole tank and refresh the filter.
Many turtle owners wonder if they need to keep the light on in their turtle's tank at night. Luckily, the answer to that is no. Your turtle will be just fine if the light is turned off during night time hours. It is actually recommended that they are exposed to a natural amount of light and darkness each day.
Aquarium Size - Your pet turtle is a strong swimmer and needs plenty of water to swim around in. A good rule of thumb is that an aquatic turtle aquarium should be 10-gallons (40-liters) of water per 1 inch (2.5 cm) of turtle shell. Make sure to have an area at the top of the tank that's above water for them to bask.
Most often, turtles try to escape their tanks because the tank does not provide a suitable habitat. Whether the tank is too small, dirty, or does not provide enough stimulation, turtles will try to escape.
A pet turtle likes to play in its tank as well as outdoors. You can play with your turtle in its tank by placing an obstacle maze, rafts, empty shells, plants, and sticks inside it. You can also make a play area outdoors where you can make a water pool or arrange a race to play with your pet turtle.

Here are some good rules of thumb for frequency of feedings:
- Feed babies and juveniles (turtles up to 1 year of age) once a day.
- Young adults should be fed every other day.
- Mature turtles should be fed every third day.
Do not use tap water for your tank, as tap water contains chlorine and possibly fluoride which can upset the pH balance of your system. De-chlorinated water needs to be used for the swimming area and filtered water for your turtle to drink.
What do turtles do at night?
During the night most turtles sleep underwater. If a turtle can't get underwater to sleep it will usually try to find a safe spot like a hole in the ground, a pile of mud or leaves, or a pile of rocks. Pet turtles will also sleep in their basking area.
-- are diurnal. During the day, these turtles hunt for food, find mates and bask on exposed rocks and logs. Sleeping behavior among these turtles is highly individualistic and different members of the same species may choose to sleep underwater or on an exposed rock, log or sandy beach.
Smaller or juvenile turtles will eat heartily every day. As they get older, adult turtles may be offered a good-sized portion of food every two or three days.
The MINIMUM amount of water in your aquarium would be FIVE TIMES the length and width of your turtle. For example, a turtle with a 10” shell length would need a tank at least 50” long. And if that turtle was 3” high at the tallest point – the water depth would be a minimum of 15”.
If you leave for a maximum of two weeks, your turtle should be just fine. Water won't evaporate that fast, and the dirtiness of the water will be tolerable. But if you leave your turtle alone for more than two weeks, you definitely need somebody to come over and change, or at least refill the water.
