Wildness has its problems and advantages. The most dangerous part of a turtle’s life is its youth. The first few years of their life has the biggest impact on their life. 

However, if a Red-Eared Slider lives long enough to become an adult, its life expectancy is far more than the life expectancy of a captive turtle. 

A wild Red-Eared Slider can live up to 70 years due to the natural habitat factors and the constant training of their immune system. Also, the volume of water they live in nature cannot be compared to the water tank in your home. 

Even the biggest water tanks that can be bought are severely smaller than their natural habitats. 

How Long Do Red-Eared Sliders Live in Captivity?

Captive animals are often living a lot less than the wild ones. Their natural habitat is broken, and their instincts cannot adapt to your water tank is, shortening their lives significantly. 

However, there are some advantages to captivity. The first and most important is a stable and rational diet. In wildness, turtles are not as secure as in captivity.

Factors Affecting A Red-Eared Slider’s Lifespan

Your turtle’s lifespan can variate from many external and internal factors. However, you can control the majority of them. Thus, you can either lengthen or shorten your turtle’s life. 

Here are the most important factors that have the greatest impact on your turtle’s health and well-being. 

Food

Food is practically the most important factor in your turtle’s life. The food you are purchasing for your Red-Eared Slider directly affects its health. 

Therefore, your turtle’s diet needs to be as perfect as possible. A young Red-Eared Slider needs to be fed every day, whereas an adult needs to be fed every 2 or 3 days. 

The food you are giving is also very important. Don’t try fireflies. They can contain a toxic substance that is slowly killing your animal. 

Also, try to avoid avocado, onions, and chocolate. They are poisonous to your turtle and cause massive health problems and many veterinary bills.  

The proper diet for a Red-Eared Slider looks this way. The main course should always be high-quality turtle food bought from pet stores. Don’t choose the cheapest option. It will only lead to treatment costs afterward. Also, try and combine turtle food with green leaves. They love spinach, kale, romaine lettuce, and other such greens. 

Occasionally, you can give your turtle a treat. It can include fruits such as apples, melons, and mangos. Also, you can give your turtle a veggie. They love broccoli, carrots, and green beans. Ultimately, there are protein snacks such as worms, shrimp, or little fish pieces. 

Captivity vs. Wild

Turtles raised in captivity live a lot less than turtles raised in wildness. That is because, in their natural habit, Red-Eared Sliders have a lot more space and opportunities to grow. Also, living side by side with other species can increase their lifespan. 

Whereas, Red-Eared Sliders grown in captivity do not have the same conditions as those raised in wildness. However, they have a lot of other advantages. First of all, captive turtles have a balanced diet and no predators to hunt them. 

Another factor that influences lifespan is exercise. Wild turtles obviously have more space and need to swim and walk, whereas the turtles raised in captivity cannot walk and swim for long periods of time.

The most common diseases for Rea-Eared Turtles are shell rot and respiratory infections. Respiratory infections can be detected by common symptoms such as loss of appetite, runny nose, and inactive behavior. These kinds of infections are usually treated with antibiotics 

Another common disease is shell rot. It is caused by fungus or bacteria and, if left untreated, can spread to other parts of the body. It can be detected by a light spot on your turtle’s shell. 

Activity
