7 Possible Reasons For Bearded Dragon Black Spots

Bearded dragons are a popular type of lizard, often kept as pets. They may develop black spots on their skin, which can be concerning and worrisome for owners.

This article will discuss seven potential causes of these black spots in bearded dragons, including:

  1. Melanoma
  2. Fungal infections
  3. Vitamin imbalances
  4. Bacterial infections
  5. Injury or trauma
  6. Environmental stressors
  7. Parasites

Understanding the reason behind these discolorations can assist owners in providing adequate care to their pet lizards.

Key Takeaways

  • Melanoma and fungal infections can cause black spots on bearded dragons and should be diagnosed and treated by a veterinarian.
  • Nutritional imbalances, including vitamin deficiencies, can lead to black spots and other health issues in bearded dragons. Supplementation and dietary changes may be necessary for proper nutrition.
  • Environmental factors, such as diet changes and stressors, can contribute to the development of black spots in bearded dragons. Proper management of environmental conditions is crucial.
  • Infections, including bacterial infections and parasites, can cause black spots in bearded dragons. Prevention through proper husbandry, hygiene, and sanitization techniques is important.


Melanoma is a possible cause for black spots in bearded dragons. It is a type of abnormal growth on the skin that can cause discoloration. Melanomas are usually benign, but can become malignant if they grow too large or remain untreated.

They often appear as dark spots or patches on the skin and may be itchy or painful. Proper diagnosis by a veterinarian is important to rule out other possible causes of the spots and determine treatment options, which may include topical creams, laser therapy, or surgery.

Fungal Infection

Fungal Infection has been identified as a cause of discoloration in certain reptilian species. It can cause black spots on bearded dragons, and should be taken seriously if spotted.

To prevent fungal infection, here are 3 steps:

  1. Keep the environment clean and hygienic.

  2. Monitor the humidity levels in the habitat regularly.

  3. Seek early diagnosis and treatment with a veterinarian for any signs of illness or injury.

Fungal prevention is key for maintaining healthy reptiles, so proper diagnosis is essential for successful treatment and prevention of future outbreaks.

Vitamin Imbalances

Bearded dragons require a balanced diet to remain healthy and prevent vitamin imbalances. Deficiencies can cause clinical signs such as poor growth, bone deformities, anorexia, and even mortality if left untreated.

Supplementation may be necessary for optimal health, depending on the individual diet of the dragon; dietary changes may also be necessary to ensure proper nutrition.

Deficiency Symptoms

Black spots on a bearded dragon may be the result of a nutritional deficiency. Symptoms can include:

  • Inadequate calcium intake which can lead to metabolic bone disease
  • Vitamin A Deficiency, causing eye issues and skin irritation
  • Genetic predisposition that leads to changes in pigmentation.

Poor nutrition can result in health problems, so proper care should be taken to ensure that your pet is getting the right balance of vitamins and minerals for optimum health.

Supplementation Needs

Supplementation of essential vitamins and minerals may be necessary to ensure a bearded dragon’s optimal health. Poor nutrition, due to improper lighting and temperature fluctuations, can lead to black spots or other deficiencies.

A well-balanced diet supplemented with calcium, vitamin D3, multivitamins and phosphorus is recommended for healthy growth. If dietary needs are not met, supplementation should be used to help maintain the proper levels of nutrients for the bearded dragon.

Regular veterinary visits are also helpful in identifying any nutrient deficiencies or health issues that could cause black spots.

Diet Changes

In addition to supplementation needs, another important factor in the health of a bearded dragon is their diet. Diet changes can be beneficial for many reasons, such as improving overall nutrition, enhancing heat regulation, and providing veterinarian care when needed.

It is essential that these changes are done with caution and under the guidance of an experienced reptile-specializing veterinarian in order to ensure the safety and wellbeing of your pet. Any dietary alterations should be monitored closely for potential adverse reactions or complications.

Bacterial Infection

Bacterial infection is a common cause of black spots in bearded dragons. It is usually caused by poor husbandry and hygiene, such as overcrowding in a terrarium or an unclean environment.

Treatment for bacterial infections can include the administration of antibiotics, antifungals, and other drugs depending on the severity of the infection.

In addition to medications, proper husbandry and environmental hygiene are essential to prevent recurrence in affected animals.


Environmental factors can be a cause of black spotting in bearded dragons. Spontaneous spotting, age related spots, and exposure to UV light are common environmental factors that may lead to the appearance of black spots. These spots can appear with no warning, making them difficult to prevent or treat without knowing the cause.

Proper enclosure setup and maintenance is key for protecting your dragon from health issues caused by environmental triggers. Additionally, providing a nutrient-rich diet with appropriate levels of calcium and other vitamins helps keep your dragon healthy and less susceptible to various diseases.


Treatments for black spotting in reptiles may involve dietary changes, the use of antibiotics, or removal of affected areas. Disease prevention and preventative care are key to helping reduce and manage this condition.

Providing adequate nutrition with proper supplementation is important, as is regular shedding and monitoring for other potential health issues. When all else fails, surgery may be necessary to remove any diseased tissue. An experienced reptile veterinarian should always be consulted before attempting any treatment option.

Injury or Trauma

Injury or trauma may be a cause of black spots on bearded dragons. Accidental trauma, environmental hazards, or genetic predisposition to disease can all contribute to this condition. These factors include:

  1. Direct contact with sharp objects or rough surfaces in the environment.
  2. Genetic disorders that can lead to abnormal cell growth and organ dysfunction.
  3. Exposure to extreme temperatures or sudden changes in temperature that can lead to burns or other forms of skin damage.

With proper care and attention, these problems can be managed and prevented from recurring.

Environmental Stressors

In addition to physical injury or trauma, environmental stressors can also cause black spots in bearded dragons. Unfavorable physical conditions such as temperature fluctuations, light levels, humidity levels, and other environmental factors can contribute to an increase in stress levels for the dragon.

Poorly managed or extreme changes in their environment can cause a disruption of their natural behavior patterns which may result in the development of black spots along their body.


Parasites can also be a cause of the formation of dark spots on the body of a reptile. Common parasitic diseases for reptiles include:

  • Intestinal parasites
  • Skin parasites
  • External parasites.

These are typically contracted by exposure to contaminated food or water sources, as well as contact with other animals. Prevention is key, and owners should practice proper sanitization techniques and use preventative measures such as regularly washing hands or utilizing gloves when handling their pet.
