Nevertheless, both types of turtles will live for exceptionally long periods of time and require long-life commitments. But keep in mind that the level of care you give your turtle significantly affects its longevity.


A box turtle is mainly terrestrial but it goes into the waters once in a while. This means its enclosure should be made up of an extensive land area to roam around.

In addition, you should provide it with a water bowl where it can walk into or even completely soak in. Note that a box turtle can be housed in an indoor enclosure or outdoor pen.

The ideal box turtle habitat should include a spacious tank to provide plenty of space for roaming, digging, and exploring.

It should also feature a comfortable basking area, powerful filtration system, heat source, and UVB light.

If you want, you can house your slider in an outdoor pond in warmer climate areas. In this case, you should properly secure the pond to keep out predators.


When it comes to diet, the two turtle species are omnivorous and require both plant and animal matter for a balanced diet.

Red-eared sliders, in particular, should be fed a variety of fruits and vegetables as well as animal-based proteins such as earthworms, small fish, mealworms, etc. You can also feed them commercial turtle pellets.

For a balanced diet, fruits and veggies should make up 50% of their diet while the rest should go to animal proteins (i.e., 25% prey food items and 25% turtle pellets).

Red Eared Slider Diet

Box turtles should eat at least 50% fruit and vegetables like green cabbage, raspberries, blackberries, papaya, grapes, butternut, apples, etc.

And the other 50% should be made up of prey items such as crickets, earthworms, mealworms, caterpillars, snails, etc., and commercial box turtle pellets (25%).

However, note that young box and red-eared slider turtles tend to eat more insects and small amphibians while the older ones are more herbivorous.

Behavior and temperament

Box turtles are less friendly and solitary creatures, so they don’t like being handled by people. While they typically don’t bite, the anxiety they get due to over-handling may cause them to nip you.

Once they get used to their new home, however, they may learn to recognize you and beg for food or even follow you from inside their enclosure.

Box Turtle Behavior

Red-eared sliders are pretty active species and you’ll often watch them diving and swimming in their enclosures. Also, captive red-eared sliders are friendly and more outgoing compared to the wild ones.

They don’t have the instinct to scratch or bite you in case you touch it. However, sometimes your pet may feel more nervous when you handle it and retract into its shell or try to nip you. That’s why always advise you to minimize handling.

Legal protections and conservation status

It’s illegal to pick a box turtle from the wild for keeping as a pet in most states. This is due to the dwindling population of box turtles in the wild.

As such, you’d want to confirm with your local regulation on box turtle ownership, including the number you’re allowed to keep.
