Before buying a pet, you always want to do your due diligence. Many a pet has wound up on Craigslist or donated to a different owner because their first owner was not properly prepared. Truly, some pets take much more work than others. Turtles make wonderful first pets and are relatively low maintenance — especially small turtles. A common occurrence with pet turtles is that owners will buy the wrong breed and they seemingly never stop growing! That means they have to upgrade to a massive tank or find a new home for their surprisingly big turtle that they may have grown attached to. In this post, I talk about the types of pet turtles that stay small and provide my readers with an overview of turtle breeds.

There are many names for small turtles such as miniature turtles, dollar turtles, quarter turtles, and dwarf turtles. It is important to note that all these are names for the same thing: very small turtles. In our first section we have a list of the top breeds of turtles that stay small and the next section is our list of turtles you should be careful about buying if you don’t want a large turtle. By looking over those sections, you’ll find information that will help prevent you from buying the wrong type of turtle for you.

What Kind of Turtles Stay Small? Raising Turtles & Overview of Turtle Species

Musk Turtle - Pet Turtles that Stay SmallTurtles are one of the most popular exotic pets and some turtle breeds have found there way into the top reptile pets. Small turtles are adorable reptiles that make a convenient pet for both apartments and homes. They require less space and less time to take care of than most other furry pets and reptiles. There are over 250 species of turtles in the world. Only a select handful of these actually stay small even in adulthood. Many people want these types of turtles because they become more feasible to care for and find a suitable tank.

Don’t think raising a turtle is a walk in the park though! A small turtle is just like any pet. They still want your love and attention. A pet turtle will need your care to grow up and stay healthy. Regular tank maintenance is required unless you want your poor turtle living in yucky and less than ideal conditions. You’ll want to clean your tank about every 3 weeks. Other than a tank, you may want a pet carrier or container as well for your little turtle. This will give you a place to put the turtle during cleaning session quarantines and trips to the vet. Turtles need to be fed about 4-5 times a week and their water source should always be as fresh as possible.

It is very important to stay aware of the differences in size between male and female turtles. As a general rule of thumb, males are typically smaller than females. It is very rare for a turtle to stay tiny, but you can find turtles that stay under 5 to 6 inches. Just because they stay small, you still want to buy a nice sized aquarium so they can stay active and healthy. Fortunately, you don’t need to spend a fortune like you would with some types of turtles. Before purchasing any pet, it is always a good idea to give the decision a lot of thought. Sleep on it. Do your best to determine if you are ready for the responsibility. The next step is the fun part: deciding what type of pet to buy.

Species of Turtles that Stay Small:

Here is our list of the best breeds of turtles that stay small. All of these turtles are readily available in the United States. These turtles usually stay smaller than 5 inches. Keep in mind that it is illegal to commercially sell turtles smaller than 4 inches. This being the case it is still legal to keep, breed, and give away these turtles to others. For example a turtle breeder could breed miniature turtles and give these away to friends or family.

What Kind of Turtles do not Stay Small?

There are a few types of turtles that are pretty common and actually end up growing to be pretty big (relative to the turtles in the above list). Some rascally pet shop owners may try to pass one of these turtles off as a turtle that will stay small, but don’t be tricked. Many times they’ll try to pass red-eared sliders off as miniature turtles because they stay small for awhile. These turtles can actually reach up to 14 inches long depending on the gender. If the turtle is green with orange cheeks (nearly red) you’ll know it is a red-eared slider.

If you are looking for a type of turtle that stays small you don’t want to try your luck with the following list:

  1. Red-Eared Slider
  2. Wood Turtle
  3. Map Turtle
  4. Western Painted Turtle

Every once and awhile there is an outlier in the above group that stays small. However, in general this list of breeds will become much larger than the list of turtles that stay small.

Best Breed of Turtles that Stay Small: The Musk Turtle

The best beginner turtle for a new turtle owner would be a common musk turtle (sternotherus odoratus). It is a member of the family Kinosternidae. The musk turtle is an aquatic turtle. They are a hardy type of turtle and make great pets. Musk turtles usually have a dark brown or black body with yellow markings.

They are very inquisitive, like to explore, and are sometimes like little mountain climbers the way they will cruise around aquariums. Unlike some species of turtle, they are not very susceptible to shell diseases or other types of illnesses. The types of mud turtles are razorback, loggerhead, flattened, and common.

Musk turtles rarely, rarely grow beyond a length of 5 inches. They are your best bet if you’re looking for a turtle that stays small forever. As I mentioned before, musk turtles may live up to 50 years old in a tank. The ideal tank for a musk turtle should be fitted with a slab of slate or a log for basking, a spotlight will a low-wattage bulb (~40-watt), hiding spots, climbing areas, and feeding spot. A 20 gallon tank is sufficient for a single adult musk turtle. 40 gallon tank can house a pair of musk turtles.
