Yellow Bellied Slider vs Red-Eared Slider – What is the Difference?

Yellow-bellied sliders are just as popular pets as red-eared sliders, and many people tend to confuse the 2.

It’s understandable because they are similar in many aspects, but they’re also quite different. It’s also normal to love both of them equally due to their easygoing personalities and great presence.

But which is better for you? Today, we will figuratively dissect these 2 species to highlight each turtle’s profile and requirements, so you can figure that out yourself.

What is a Yellow-Bellied Slider?

The yellow-bellied slider (Trachemys scripta scripta) is a species of freshwater turtle native to the southeastern United States. It is a subspecies of the Pond Slider (Trachemys scripta), which also includes the Red-eared Slider (Trachemys scripta elegans) and the Cumberland Slider (Trachemys scripta troostii).

These turtles are more widespread in semi-aquatic habitats, as they prefer to frequent ponds, lakes, marshes, swamps, and any other body of water with heavy vegetation.

Yellow-bellied Sliders are named for their yellow plastron (the underside of their shell) and the distinctive yellow markings on their heads and legs. They have a smooth, oval-shaped shell that is typically greenish-brown with dark markings.

They can grow up to 12-13 inches in length and live up to 30-50 years in captivity, although some turtle keepers have claimed vastly longer lifespans.

What is a Red-Eared Slider?

The Red-eared Slider (Trachemys scripta elegans) is a species of freshwater turtle that is native to the southern United States and northern Mexico.

It is a subspecies of the Pond Slider (Trachemys scripta), which also includes the Yellow-bellied Slider (Trachemys scripta scripta) and the Cumberland Slider (Trachemys scripta troostii).

Red-eared Sliders are named for the red stripe behind their eyes, which is more pronounced in juveniles. Interestingly, though, these reptiles possess more yellow than the yellow-bellied sliders.

While the former only have yellow markings on the head and plastron, red-eared sliders even come with yellow shells, especially as juveniles. Adults tend to become more brownish as they mature.

They have smooth, oval-shaped shells with dark markings. They can reach 12 inches in size, sometimes even more. Also, they can live for decades in captivity, which is typical for turtles and reptiles in general.

Red-eared Sliders are popular as pets because of their attractive appearance and relatively easy care. However, these turtles rank as invasive reptiles in some areas due to their hardiness and insatiable appetite, and competitiveness with native turtle species for resources.

It is important to only keep Red-eared Sliders as pets if you are committed to providing them with proper care because they are not exactly easy to maintain over the years.

Red-eared Sliders are found in a variety of aquatic habitats, including ponds, lakes, marshes, swamps, and slow-moving streams and rivers. They prefer habitats with plenty of aquatic vegetation, basking sites such as logs or rocks, and clear water with a moderate current.

These ecosystems provide the animal with a variety of resources and shelter, which contribute to its long lifespan, even in the wild.

Comparison: Yellow-Bellied vs. Red-Eared Slider

These 2 species have more things in common than you might expect.

So, let’s look into those:

Habitat and Distribution

Both reptiles are found in the southern US, where they inhabit a variety of bodies of water. They prefer regions with thick vegetation and slow-moving waters where they hide and hunt.

Their coloring allows them to hide in the dark and heavily planted waters to escape predation and increase their survivability.

The shared ecosystem increases the confusion between the 2 species, especially when you only get a glimpse of them as they run to safety.

These turtles are rarely seen on land, but they will leave their aquatic ecosystem at times to bask or even lay eggs.


While the turtles may appear similar at first glance, they have several distinct physical characteristics to consider.

For instance, yellow-bellied sliders have a yellow plastron (underbelly) and a black head with yellow markings. The reptile showcases more yellow on the neck.

Red-eared sliders have a similarly-colored shell, but they don’t possess as much yellow on their heads and neck. The most noticeable features are the 2 elongated red markings on each side of the head.

These markings are responsible for the turtle’s name and should serve as the best separating characteristic between the 2 species.

Size & Growth

Unfortunately, you can’t use these species’ size and growth rates to differentiate between them. They both grow at pretty much the same rate and can reach 12 inches at most, with some exceptions.

There have been reports of turtles reaching 14 inches in both species, but these are rare cases that are not representative of the majority.


Fortunately, both species have pretty much identical requirements in captivity. They enjoy the same conditions in the wild and even inhabit the same regions; it only makes sense that they demand similar housing conditions and parameters.

As general recommendations, consider the following:

  • A good and stable temperature gradient with temperatures around 72-80 F for the general area and 90-95 F for the basking spot
  • A larger source of water, like a personalized pool or an improvised mini-pond
  • At least one main covered hiding zone
  • A stable day/night cycle for a good circadian rhythm
  • A natural-looking layout with rocks, plants, logs, and other useful decorative elements
  • UVB lights for adequate vitamin D production and calcium absorption
  • A varied omnivorous diet, combining fruits, veggies, insects, and meat, based on specific recommendations
  • Regular vet checkups to keep the reptiles in good health and avoid injuries, infections, and parasites
  • Food supplementation to prevent calcium deficiency, which can lead to Metabolic Bone Disease and other health problems

Always learn everything you can about each species, so you can provide your turtle with personalized care.

These are merely standard recommendations that you can and should adjust to meet your pet’s unique preferences and needs.


Both species are almost identical in terms of behavior. These turtles tend to be extra shy and reclusive at first until they get accustomed to their new home.

They should become more open and exploratory over time as they become familiar with your presence. Neither of these reptiles is aggressive toward humans, but you should always be wary of their behavior.

After all, they are reptiles and don’t like being over-handled or petted. They can even bite in some cases if they’re stressed or scared enough. Other than that, both species are diurnal, so they should be fairly active during the day, especially in the morning.

Keep in mind that their activity levels tend to drop in the afternoon when they prefer to bask and digest their meals.


You can handle them both with the same ease, but you should be careful about it. As I’ve already mentioned, reptiles aren’t that fond of human interactions, so frequent handling can stress them out.

You should always be careful how you handle them, especially if the turtles are mature and carry more weight.

Make sure you support the animal’s weight properly to prevent injuries and always handle it with care and attention.

Don’t make sudden moves that could scare your turtle, and place the reptile back into its enclosure if it exhibits signs of discomfort, fear, or aggression.


Both turtles live up to 30 years in the wild, on average, and up to 50 years in captivity. These are general numbers that may or may not represent your turtle.

It’s important to note that turtles tend to live longer in captivity due to the lack of predation, top veterinarian assistance, and nutritious and regular meals.

At the same time, not all turtles reach the same lifespans, not even in captivity. The quality of care, diet, stress levels, and the reptile’s gene pool all influence its lifespan and quality of life one way or the other.

Care Level

Both turtles qualify as moderate in terms of the difficulty of care. They don’t need specialized care, but they’re not meant for complete beginners either.

Ideally, you should possess at least some level of experience in caring for turtles or even reptiles in general.

You can also educate yourself even further on the turtles’ behavior and requirements so you know what to expect going forward. Finally, don’t shy away from asking for professional help in case you can’t figure things out.

Doing so can help you understand your pet’s needs better and improve its quality of life considerably as a result.

Health Problems

Neither of these turtles is prone to any health issues. They’re generally dealing with the same conditions that plague the reptile world, to begin with.

These include nutritional deficiencies (increasing the risk of MBD), respiratory and skin infections, parasites, bacterial infections (mouth rot, tail rot), dysecdysis (abnormal shedding), etc. The only health condition that’s specific to turtles is shell rot, which is typically a bacterial or fungal infection.

It’s important to monitor your turtle’s health status regularly to prevent life-threatening conditions over the years. Also, keep the reptiles in clean and sanitized ecosystems, feed them a balanced and nutritious diet, and take them to regular vet checkups to keep them healthy and happy.

Keep in mind that you might need your vet’s assistance more often than you’d expect. Many health problems come with a variety of symptoms, which are also often associated with other conditions.

So, only a veterinarian with experience in reptiles and turtles can diagnose your pet’s condition accurately.

Price & Cost

Yellow-bellied turtles fall in the $30-$100 range, depending on the specimen, while red-eared sliders are cheaper, usually around $15-$40 per specimen. It’s important to note that the prices can vary drastically based on a handful of factors.

These include:

  • The turtle’s age, size, and morph
  • The local competition in the market
  • The number of turtles available for sale in your area
  • Any laws and regulations that limit or condition the trade and ownership of turtles, which can increase the pricing
  • Where you’re getting your turtle from (private sellers tend to have higher prices than regular pet shops, but the quality also matches the pricing), etc.

Take your time before deciding on the right turtle. After all, you’re looking to acquire a turtle pet that’s set to live for you for decades to come. Patience is key in this sense.

Diet & Feeding

There’s a lot to discuss at this point, but we’ll keep it short.

Here are a few tips to consider:

  • Both turtles have an omnivorous diet because they pretty much live in the same ecosystem
  • Both require one meal per day at least, depending on their age, size, and appetite
  • Veggies, fruits, and animal protein should be cycled regularly throughout the week for a varied and consistent diet
  • Consider vitamin D and calcium supplementation in case your turtle needs it (speak to your vet about it)
  • Prepare the food accordingly (wash, peel, and cut veggies and fruits and cook the meat to eliminate the risk of parasites or bacterial infections)
  • Fruits should be limited, as they carry too much sugar, which promotes obesity
  • Adult turtles eat less animal protein than juveniles

Ultimately, what and how your turtle should eat depends strictly on the turtle itself. Start with the standard recommendations and adjust your turtle’s meal type, size, and frequency based on its needs and preferences.

Yellow-Bellied Slider vs. Red-Eared Slider – Which Makes a Better Pet for You?

There isn’t a definitive answer to this one. The most honest answer would be: whichever you would prefer. Both species have similar requirements and do the same in captivity.


You’re looking at 2 different yet very similar species that both make for great pets in ideal conditions.
