Can Turtles Eat Blueberries?

Turtles, while being one of the smallest pets you can possibly have, require the most care and attention you can have. Therefore, turtle owners must stick to a very strict and balanced diet with the right vegetables and fruits. 

Now, can turtles eat blueberries? 

The short answer is yes, turtles are able to eat blueberries. However, you must regulate their blueberry intake very carefully as the levels of acids and sugar are very high. These components can lead to very serious health issues. 

Are Blueberries Toxic for Turtles?

No, blueberries don’t contain any unhealthy toxins that can have a negative impact on your turtle’s health. However, there are some things to talk about when it gets to the healthiness of the blueberries for your turtle. 

While turtles can eat blueberries, it isn’t very healthy for them to eat a lot. Due to the high content of sugar and acids, blueberries can cause some serious health problems. Here are some more informative descriptions of these two components. 


Blueberries contain a lot of sugar. When I say a lot, I mean it. 100 grams of blueberries contain up to 10 grams of sugar in form of glucose or fructose. That much sugar can easily kill your little pet. Therefore, you should restrict the number of blueberries in your turtle’s diet. 

The most alarming health issues related to high sugar intake are cholesterol spikes and insulin resistance. These two conditions can completely mess up the internal balance of your turtle and slowly drive them towards death or serious health problems. 

Another thing to worry about when thinking about high sugar intake is the stomach. Turtles aren’t the strongest species and their stomach can prove that. Their digestive system can get upset very easily and that leads to indigestion, loss of appetite, and other problems. 


Blueberries, besides other acids, primarily contain citric, quinic, and malic acids. However, it’s not the types of acids that make blueberries dangerous, but their quantity. Blueberries are loaded with different acids that your turtle won’t really appreciate eating. 

The high acid intake can lead to a disbalance in your turtle’s stomach pH, wipe out colonies of good bacteria and lead to high levels of toxins in the bloodstream. Also, it can mess up the digestive system, giving your turtle trouble digesting food and absorbing needed nutrients.


Pesticides and other toxic chemicals are used to grow and harvest practically every type of fruit and vegetable. Blueberries are no exception. The ones you buy at the market are covered with unhealthy no matter how healthy and organic they seem. 

You understand that giving your turtle treats that, besides their nutritional value, bring some toxic chemicals into the aquarium, isn’t the best idea. Therefore, make sure you wash and soak the blueberries in freshwater before giving them to your turtle. It will completely remove the chemicals and will make them safe for your little friend.  

Are Blueberries Healthy for Turtles?

Yes, in small quantities blueberries are very healthy for your turtles. As an occasional treat, blueberries provide high levels of vitamin A and C. 

Vitamin A is responsible for the health of the eyes and lungs. As you may already know, respiratory problems are one the most encountered for pet turtles. Therefore, a high vitamin A intake can lead to the absence of these issues.  Also, vitamin A helps with the regular functions of the skin and different organs. It is stored in the turtle’s liver and used constantly to build and heal some minor issues. 

Vitamin C, on the other hand, is responsible for a strong and healthy immune system. It boosts the immunity to minor infections and can keep some fungal and bacterial issues at bay. Water is a pretty good environment for the spread of different bacteria. Therefore, food rich in antioxidants and immune boosters surely helps minimize the risks of infections. 

How Many Blueberries Can I Give My Turtle?

Blueberries, being dangerous to turtles in high quantities, are meant to be occasional, tasty treats. The best way to feed your turtle some blueberries is once or twice per week. This way, they will take all the beneficial nutrients and vitamins without getting poisoned by the high sugar and acid content of blueberries. 

For mature turtles, two to four blueberries as a special treat work perfectly. However, it also depends on the size, type, and age of your turtle. You can’t feed the same quantity of blueberries to a little turtle as you’ll feed an adult, big turtle. The best way is to make the blueberries intake a part of the regular diet with a 5% stake. 

How to Feed Blueberries to Your Turtle?

The best way to feed your turtle some blueberries is to cut them into halves, remove the seed and feed them. However, there are some particularities to talk about here. 

First of all, you should be very careful with baby turtles. You can give them blueberries, of course, but make sure you cut them into little pieces and remove the skin. The skin is a little hard and can cause choking for little turtles. 

Also, make sure your turtles can catch the little fruits. They are little and can be a little tricky to eat for your reptiles. They will swim around and try to eat those tiny pieces for a long period of time before you’ll help them.
