White Spots on Turtle Shell – Detailed Treatment Method

White spots on a turtle’s shell are a pervasive issue. However, luckily it is a problem that is easy to fix. White spots can occur as small areas or large regions. It can also be found on the neck and legs. Mineral deposits, shell rot, loss of the skin, etc., are the three primary reasons for these spots.

The difficulty is that these problems can be hard to distinguish. Hence, it’s critical to figure out what you’re up against before taking any action. We’ll go through how to recognize, treat, and avoid each of them in-depth in this article. We’ll also give you information on when to consult the vet to cure these white spots.

White Spots on Turtle Shell: Major Cause

White spots on a turtle’s shell can be caused by a variety of factors, including fungal or bacterial infections, calcium deficiency, or injury. It is important to seek veterinary care if the white spots are accompanied by other symptoms, such as lethargy, appetite loss, or difficulty breathing. Proper nutrition and maintaining a clean habitat can help prevent the development of white spots on a turtle’s shell.

Reasons for spots on a Turtle’s Shell 

There are various reasons why your Turtle’s shell will start having white spots. The three most predominant reasons are as follows: 

1. Mineral Deposits

Reasons for spots on a Turtle’s Shell - Mineral Deposits

You may see white spots collecting on just about any section of glass in your pet’s aquarium where the water has dried. This is most likely to happen if you have hard water. Properties like calcium carbonate and magnesium are abundant in hard water. None of these substances is indeed harmful to your pet. However, calcium carbonate dries on the animal’s shell after it exits the water, which gives it a white, chalky look.

Mineral deposits on a turtle’s shell almost always have large areas that turn white rather than small spots scattered all over the shell. Because it is out of the water, the top half of the shell, called the carapace, often turns white. If you notice your turtle’s shell goes white in significant places but exhibits no signs of illness, it’s most likely due to mineral deposits. Take some vinegar and apply it to one of the white places to be sure. The vinegar’s acetic acid will induce a significant bubbling response if calcium carbonate is the culprit. This does no harm to the turtle and indicates that hard water is to blame.

2. Shell Rot

Shell rot is also known as ulcerative shell disease. It is referred to as a bacterial or fungal infection of the shell. Shell rot typically begins with little patches and spots rather than the enormous regions observed with mineral deposits. It can take on a variety of appearances depending on the pathogen that causes it. These spots become more prominent with time. It later results in bright red patches, bleeding, mushy areas, dents, and pitting. Shell rot is a dangerous disorder that affects the bones rather than the shell. If not appropriately treated, Shell rot can lead to septicemia or fatality.

So, how do you identify a shell rot? If you notice your Turtle’s shell showing dents, exhibiting small holes, etc., shell rot is a strong possibility. 

3. Shedding of scutes and skin 

The skin of all turtles shed. The scutes of most aquatic turtles are also shed. This keratin renewal enables development and aids in the removal of algae and grime. The new shell or skin should be brilliant, colorful, and clean after ecdysis.

The shedding scutes are relatively thin and peeled off in a single transparent layer. Shed skin might be in little bits or strands that resemble white thread or cotton-like substances. When a turtle is immersed, healthy shedding skin can hang off the neck or limbs and hover. It appears as white or grey spots in this situation. Although, it is exceedingly thin and not noticeable whenever the animal is drying. Scutes that are shedding may have a whitish appearance. However, if looked at closely, you can notice that this is due to trapped air. In this case, they will be metallic and not mushy.

What is shell rot and what causes it in Turtles?

In turtles, shell rot is a severe medical problem. This can be affected by a multitude of factors, including injuries, shell fractures, and a polluted habitat. If the turtle merely has a slight case of shell rot, it will not appear unwell and will stay fully active.

Let’s take a closer look at the causes:

1. Injuries 

For the most part, turtle shells are strong and durable. However, they are vulnerable to catastrophic injury. Almost all of the time, it’s because of a fight with another turtle. Males are more likely to engage in these battles. Such brawls may lead to injuries, which, if ignored, might lead to significant problems later.

2. Cracked Turtle Shell

Cracked Turtle Shell

The shell of a turtle can break for a variety of causes. For instance, this might occur as a result of the enclosure’s humidity or temperature being too low. When the substrate is excessively dry, a turtle species that is used to a humid climate may develop shell or skin problems. When the substrate is excessively moist. However, a dry environment species’ outer shell softens, allowing infective agents to penetrate. Aside from that, inadequate nourishment, incorrect warmth, and sharp items in the cage can cause corrosion in the shell. If the cracks aren’t repaired quickly enough, shell rot can occur.

3. Inadequate tank conditions

Because turtles like to eat and excrete in the water, their tank may quickly become filthy. As a result, you’ll need to replace the water frequently and maintain a strong filtering system. Shell rots are more common in species with softer shells, like as red-eared sliders, that live in a polluted environment. Dirty or moldy bedding, in addition to filthy water, can cause shell rot. As a result, make sure to clean it regularly.

Hard water and your turtle

Although it may seem strange, hard water is a common cause of white markings on turtle shells. The shell is generally uniformly covered in white in this case.

These dazzling white spots can be easily removed with moderate cleaning or rubbing.

Applying a drop of vinegar to the lesion and watching it fizz is the easiest way to see if the spots are visible due to hard water. If it occurs, the white areas are very certainly caused by calcium carbonate in hard water.

What is hard water?

Hard water is known as water that contains large amounts of minerals such as calcium and magnesium. The water evaporates when you have hard water, leaving mineral remnants behind. You can generally find mineral deposits on shower faucets, sinks, bathtubs, and even on cups and glasses.

Fungal infections are fairly frequent, and if caught early enough, they are not hazardous. Firstly, you must understand the fundamental causes behind this. Inadequate water quality and a lack of adequate basking areas are the most common causes. Because turtles prefer to eat and excrete in the water, the water in their tanks tends to grow dirty rapidly.

As a result, both leftover food and trash will sink to the tank’s bottom. It creates the ideal environment for bacteria to thrive. This encourages the spread of the fungus. A turtle’s tank should be cleaned often and thoroughly. It’s also possible that warmer water in your turtle’s aquarium encourages fungus development.

Hypoallergenic soap, betadine solution, and soft-bristled toothbrushes are all required. It is important to remember that the soap has to be fragrance-free. Begin carefully cleaning the shell with the toothbrush and soap. Make sure the fungus is completely submerged in water, but don’t use a lot of soap.

After you’ve finished washing the shell, rinse the turtle with fresh, hygienic water and place him under the light to dry. You may gently pat him dry now. After he’s totally dry, use a cotton pad or bud to apply a diluted solution all over the shell. We  suggest Betadine because it’s safe for all reptiles. Use ten parts water and 1 part Betadine to produce the Betadine solution. Gently clean everything off after using the diluted iodine solution.
