Turtle shell fading is something unnatural and you should be worried when your turtle has it. It could be a sign of an underlying health problem in your turtle pet.

The discoloration could appear in the form of the shell turning pale, washed out, or simply the shell losing its vibrancy.

Why is my turtle shell color fading

This problem usually has something to do with not taking good care of your turtle.

Listed below are the main causes for fading or discoloration in turtle shells:

Lack of UV light

One of the reasons behind turtle shell discoloration is the lack of UV light. Lack of exposure to UVB rays of light limits your turtle’s ability to properly absorb the calcium required for healthy growth, and their shells will start fading.

Make sure your turtle gets enough exposure to sunlight every day to maximize its calcium absorption. If you have your turtle housed indoors, be sure to place a UVB light bulb near their tank to ensure they have sufficient exposure to the light.

Some pet owners make the mistake of not replacing their UV bulbs with time. Unknown to them, however, these bulbs tend to lose their effectiveness over time, denying your turtle proper UV light exposure.

We advise you to change your UVB light from 6 months to 1 year.

Also, if possible, take your turtle outdoors to get a real dose of sunlight. This is because no matter how expensive a UV bulb you have invested in, it can never replace the actual UVB rays coming from the sun.

Poor nutrition

If your turtle has poor nutrition, without the essential minerals and vitamins, it may also be the reason behind its fading shell. This is because the turtle will be deprived of the key nutrients needed for healthy growth and maintenance of its shell.

Luckily, this is something you can solve by improving your pet with a healthy and balanced diet. This should include not just the commercial turtle pellets but also fruits, veggies, and occasional worm feeding.

Low protein intake

Yes! If you don’t include proteins in your turtle’s diet, it may also make their shell turn pale or washed out. This is especially important for baby turtles which heavily rely on protein for proper growth.

Feeding your pet worms and insects mixed with pellets is an effective way to ensure they have enough proteins in their diet and keep off discoloration problems.

Hard water

Putting your turtle in an enclosure carrying hard water will also make its shell fade with time. But don’t get it wrong; hard water isn’t harmful to your shell’s health in any way.

However, the minerals like calcium and magnesium in the hard water will get deposited on the shell of your pet turtle scutes and make it look discolored or faded.

If you’re suspecting this could be the culprit affecting your little friend’s shell, you can try introducing a water filter in their tank to help bring down the mineral levels.

You can also make water changes using a water conditioner can also help reduce magnesium and calcium levels in the water—helping restore the turtle shell’s original color. When your turtle is basking, the water evaporates and the minerals are left on their shell, causing a discoloration.

As for the shell affected by hard water, you can try wiping it with a soft cloth to get rid of the minerals buildup. You can also try gently brushing your turtle shell with a soft toothbrush to get rid of these deposits.

NOTE: Some turtle owners mistake these mineral deposits for a fungal infection or shell rot. If the spot you’re skeptical about looks chalky and doesn’t feel soft to the touch or smelly, then you’re most likely dealing with hard water stains on your pet’s shell.

Should turtle shell colors change color?

Absolutely! Turtle shell colors do change color as these reptiles grow and age. Most newborn turtles usually feature bright green and yellow shells which then turn into darker colors as they become older.

Nearly any turtle species undergoes some degree of color change with time. Even the young ones of red-eared slider turtles usually have a bright green appearance. But as they transition into adult age, their shell will turn black, brown, or dark green.

If you want to be sure that a turtle shell color change has nothing to do with its health, observe it for any behavioral change. If it continues eating well and acting normally after undergoing color change, then there’s nothing wrong with it.

Natural and healthy color changes should also happen uniformly on every inch of the turtle’s shell.

Should turtle shell colors change color

Here are a few cases that can bring about a natural color change in your turtle’s shell:

  • Growth: The shell develops darker shades or becomes more evenly colored as your turtle grows. For instance, your baby turtle shell can change from a bright green or yellow color to black as it gets older. This is a natural occurrence that happens across nearly all turtle species
  • Shedding: Turtles also shed their scutes as they grow. This is an important phase in their life and helps keep their shell healthy and free from fungal infections or shell rot. When the shedding occurs, the underlying layer looks bright and colorful. But as it gets exposed to the light, it starts dulling down and even takes the color of the surrounding.
  • Environmental factors: Environmental factors may also be to blame for your turtle shell color changes. Turtles that live in an aquarium tend to feature a paler-looking shell compared to those that live under direct sunlight. This is because a natural environment provides the turtle with plenty of UV-B light which is necessary for helping produce vitamin D that facilitates healthy shell growth.

Note that bright colors in adult turtles are also attractive to the female turtles and help the males find a potential mating partner.

Why is my turtle’s shell turning white?

Your turtle’s shell turning white is mainly due to the hard water in its tank. As you already know, this type of water contains dissolved minerals. And these can get deposited on your turtle’s skin over time, creating a chalky substance (the hard water residue) with a whitish appearance.

As we said earlier, however, hard water isn’t dangerous for turtles and doesn’t affect their health in any way.

The good thing about the mineral despots is that you can easily get rid of them by wiping them out using a soft wet cloth or a soft toothbrush. If this method doesn’t work, you may consider consulting your vet.

Your turtle shell turning gray could be an indication of fungal infection. The gray spots or patches usually appear with the white spots discussed above and some pet owners will describe them as white-ish gray spots.

The shell fungus infection is usually caused by contaminated water or insufficient basking area (for proper UV light absorption).

Shell rot is an infection or simply a rotting of the turtle shell and can cause black spots to appear on your turtle shell. This is a serious health problem and requires immediate veterinary attention.

Placing your turtle in contact with UV light can burn its shell. This is highly possible given that some pet owners like placing their turtles directly on top of the UB bulb. Others place it too close to the basking bulb.

In either case, this can cause serious damage to your pet’s shell and should be avoided at all costs. Make sure you always maintain a safe distance between the basking bulb and your turtle friend’s basking platform.

When is turtle shell color change unhealthy?

You can tell when your turtle shell color change is healthy by looking for key signs of unhealthy shell discoloration such as patchy or uneven coloring, fading of stripes or markings, and the shell becoming lighter in color.
