Can Turtles Eat Cucumbers?

A turtle’s diet can be as varied as a human’s. There are no products, excluding those that are toxic, that a turtle cannot eat or wouldn’t eat with pleasure. From vegetables to fruit, fish, and shrimp, turtles will eat it all. 

But can turtles eat cucumbers? 

The short answer is yes, turtles can eat cucumbers. However, you need to find out more about this topic before giving your turtle some of this watery veggie. In this article, you’ll find out everything there is to know about cucumbers and their beneficial impact on your turtle’s life. Enjoy! 

Are Cucumbers Healthy for Turtles?

If you want to feed your turtles some cucumbers, you probably want to know about their health benefits. It is a fact that cucumbers are very healthy not only for turtles but also for human beings. Here are some reasons why cucumbers can improve your turtle’s health. 


While turtles are practically their whole life in water, a little bit of extra hydration won’t hurt. Cucumbers are full of water. On hot days, cucumbers are the best product to keep your turtle from dehydration and the problems that are coming with it. 

Of course, your turtle must have always fresh water to swim and drink. However, when it is not possible to provide fresh water for your turtle to drink, a cucumber-based diet should do the trick. Remember that cucumbers cannot keep your turtle fully hydrated and, after a day or two, you’ll be required to put your turtle into some freshwater. 

You can use this trick while cleaning your turtle’s aquarium or changing its environment. 

Source of potassium

Minerals are very important for turtles. Potassium, calcium, and other such nutrients are keeping your turtle healthy. The lack of potassium in the organism can lead to some serious health problems I will talk about further.

First of all, there are heart problems. Potassium is one of the most important minerals when it comes to the heart. It ensures a healthy and well-working heart and circulatory system in general. Also, potassium does a great deal regulating the work of other muscles and systems in the organism.

Secondly, without the needed amount of potassium, your turtle’s nerves and bones won’t be the same. The nerves won’t have the needed amount of minerals and will just go numb. The bones will get softer and weaker with time. 

It is a good thing that cucumbers contain a high amount of potassium and, a small dose of cucumbers every 4 or 5 days can do the magic and, with other veggies and fruits, close the need for potassium for your little friend. 

A good source of vitamin B 

Vitamins in general and vitamin B, in particular, are very important for a turtle. As you may know, turtles have weak immune and respiratory systems. Now, a good dose of weekly vitamin B can reduce the number of health issues linked to those systems. 

Now, why is that? Vitamin B is known to be one of the most important vitamins because it can improve cell health, brain function, and appetite. Also, it helps with muscle tone, hormones, and cardiovascular system health.

On top of that, it actively prevents the apparition of different infections in your turtle’s body. To sum up, vitamin B is maybe the best nutrient that cucumber can provide.

How Many Cucumbers Should I Feed My Turtle?

While cucumber has some beneficial nutrients for your turtle, it cannot provide all the nutrients specter alone. Therefore,  it can’t be used as a base of your turtle’s diet under no circumstances. As an occasional treat, cucumber works perfectly. No more than that. 

If you’ll give your turtle too much cucumber, it can lead to some minor but unpleasant health problems. Too much cucumber causes diarrhea, indigestion, and other digestive system problems. Also, it can lead to loss of appetite and a bad mood. 

How to Feed Cucumbers to Turtles?

Cucumbers are relatively big and hard veggies to eat. Therefore, there are some cautions for you to take before feeding your turtle some cucumber. Here are the safest and most pleasant ways to feed cucumbers to your little pet friend. 

First of all, remember to only feed your turtle raw cucumbers. Cooking, seasonings, and oils are not naturally available for turtles, that is why they shouldn’t eat them as much as we do. This kind of product can be very problematic for turtles to digest and can lead to serious health issues. 

Secondly, remember to cut the cucumber as small as possible. They are terrible dangerous because your turtle can easily choke on them. Also, do not try to feed pickled cucumbers to your turtle. They are way too acidic and can also have a negative impact on your turtle’s health. 

Can Turtles Eat Cucumber Peelings?

Yes, turtles can eat cucumber peelings. While you may think that they are way too hard for them, it is not the case. The problem with choking doesn’t lie with the hardness of the material but with its size. If you’ll cut the cucumber peelings small enough for your turtle to eat them without any problems, there is no choking hazard. 

The thing is that cucumber peelings cannot always be too tasty. If your turtle refuses to eat cucumber peelings one day and eats them another day, just keep in mind that cucumbers are different and the peelings it didn’t want to eat may have been bitter. 

Frequently Asked Questions

Here are the answers to some of the most important and interesting questions related to this topic. 

Can I Feed my Red Eared Slider Turtle Cucumber?

Yes, you can feed your Red-Eared Slider turtle some cucumber. However, due to its carnivore nature, I don’t think it will like to eat cucumber as much as some insects or a shrimp. 

Nevertheless, Red-Eared Slider turtles eat veggies and fruits as much as protein-packed products. Their diet is approximately 50% animal and 50% vegetal products. Therefore, you can give it some cucumber and see if it will like the taste of it.

Yes, desert turtles can eat cucumber. Like any other type of turtle, desert turtles eat veggies and fruits with no problem. However, I doubt that you should only give it cucumber. There are some other, more nutritious, and tastier products. 

The best way to give them some cucumber is by mixing it with other veggies. You can use carrots, some lettuce(not iceberg lettuce ), and cucumbers. It will be both refreshing due to the high quantity of water in cucumbers and nutritious from lettuce and carrots.

Yes, tortoises can eat cucumbers. They are natural herbivores and all types of veggies and fruits are good for them. Cucumbers are no exception. However, while tortoises may love to eat cucumbers, you should remember the fact that they are not as nutritious as they need to be. 

Also, remember about the health issues that a cucumber-based diet can cause. 


Now you know that cucumbers are perfect as an occasional, beneficial treat for your little ped friend. They do contain some beneficial vitamins and minerals. However, you can’t plan to feed your turtle only cucumbers.
