Red-Eared Slider vs Box Turtle: Detailed Discussion

In this section, I will discuss all the crucial things one needs to consider while purchasing a turtle. It’s not a particular advantage or disadvantage. Just check which features you find advantageous for you as a pet owner. 

1. Size

Box turtles are one of the smallest turtles, ranking 4.5-8 inches. It makes them much smaller than red-eared sliders, which can be 8-12 inches. The size of red-eared sliders differs based on sexuality, but not in box turtles. 

Res (red-ear sliders) have a faster-growing rate as well. They reach their full size by six to seven years. However, it may take several years for box turtles to grow fully. 

So, which one do you prefer? If you want a small one, then go for box turtles. And if your choice of pet is a slightly bigger one, then RES is your turtle. 

2. Habitat

RES are semi-aquatic, requiring a large, deep body of water for swimming. You also need to keep basking areas for them outside the water. This water area should be at least twice their shell length and allow them to fully submerge. However, like sea turtles, they breathe air. 

In contrast, box turtles primarily live on land. They only require a shallow dish of water for soaking. This dish should be large enough for them to comfortably fit inside.  While they can be kept indoors, spacious outdoor enclosures are ideal for their well-being.

Now the decision is yours. Do you like terrestrial or aquatic turtles? And remember the habitat area factor as well. 

3. Diet

When it comes to diet, both are omnivorous. So, this is not something you need to bother about. They will eat practically anything they can put into their mouth, including crackers. From fruits and vegetables to insects, they chomp on everything. Nonetheless, in the easy years of their life, they need to eat more insects. 

Red-eared sliders tend to eat more than box turtles. Here is why:

  • They are larger in size, so they need more food. 
  • Their more active lifestyle requires more energy than box turtles. 
  • Young red-eared sliders have a higher percentage of animal protein in their diet.

In that case, if you want to spend less on their food, then you may opt for box turtles. But some people enjoy watching their pets eating. RES makes better pets for such people. 

4. Activity Level

Red-eared sliders are known for their energetic swimming behavior. They have good swimming speed. These turtles are curious creatures and may actively explore their environment, both in water and on land. 

Box turtles, on the contrary, are less active. They prefer to spend more time basking or hiding under leaf litter. Their movement is slower and more deliberate compared to the fast swimming of red-eared sliders.

If you enjoy observing active animals, a red-eared slider might be a good fit. For those who prefer a calmer pet should keep a box turtle. Besides, box turtles brumate during the winter

5. Lifespan

  • Red-eared sliders: With proper care, RES can live for 30 or more years in captivity. Some individuals might even reach 40-50 years. Owning a red-eared slider is a significant commitment due to its long lifespan.
  • Box turtles: Box turtles are renowned for their exceptional longevity. They can easily live for 50 years or more in captivity, with some species reaching over 100 years!

So, both these turtles require owners who understand their long lifespans and are prepared to provide consistent care for many years.

6. Care Difficulty

While both turtles require responsible care, Red-eared Sliders generally present a greater challenge. Their large size necessitates a spacious enclosure with a deep water area. They demand regular cleaning and maintenance to maintain water quality. 

Box turtles, on the other hand, have simpler terrestrial needs. Their smaller size allows for a more manageable enclosure with a shallow water dish. Their diet also leans more towards readily available vegetables and fruits. Still, they also need insects, but occasionally. 

Therefore, box turtles are better for new pet owners. 

7. Cost

When it comes to purchasing costs, RES is more affordable. They are widely available and popular as well. In contrast, box turtles are expensive due to their rarity. Nonetheless, the overall caring cost for box turtles is less than RES. 

8. Legality

Some legal restrictions are implied on RES in certain areas because of the following:

  • Red-eared Sliders are considered an invasive species in many areas.
  • Certain states and countries completely ban the sale of Red-eared Sliders.
  • Some locations may restrict the number of Red-eared Sliders you can legally own.
  • Releasing any pet turtle into the wild is generally illegal due to ecological concerns.

These restrictions are more flexible towards box turtles.  They are typically native to specific regions and are not considered invasive. Some states might have limitations on the number of native box turtles you can possess. However, there are some specific restrictions on commercial trade. 

Important Note: Laws regarding turtle ownership can vary significantly by location.

Similarities Between Red-Eared Slider and Box Turtle

The similarities between RES and box turtles include the following:

  • Both species require a diet that includes both animal and plant matter.
  • Both enjoy basking under heat lamps or sunlight to regulate their body temperature
  • Their longevity is a common trade among turtles
  • They need access to water, though the amount varies. 
  • Both require specialized care specific to reptiles.

Which Animal Should You Go For?

Choosing between a Red-Eared Slider and a Box Turtle depends on your lifestyle and preferences:

Go for a Red-Eared Slider if you:

  • Enjoy active pets. They are more active swimmers and may provide more visual entertainment.
  • Have a large space. Their large size and aquatic needs require a spacious enclosure with a deep water area.
  • Are committed to long-term care. They can live for 30+ years, so be prepared for a long-term responsibility.

Go for a Box Turtle if you:

  • Prefer a calmer pet. They are less active and spend more time basking or hiding.
  • Have limited space. Their smaller size and terrestrial needs require a less demanding enclosure.
  • Want a lower-maintenance pet? Their simpler diet and care requirements make them easier to manage.
  • Live in an area with restrictions on Red-eared Sliders. Box turtles are generally less restricted due to not being invasive.

Conclusion
