Physical Appearance: White fungus on a bearded dragon appears as a patchy, white, cotton-like substance on the skin. It can be easily confused with shed skin, but the fungus will usually have a fuzzy texture and may be accompanied by an unpleasant smell. The affected areas may also appear swollen or discolored.

Behavior Changes: Bearded dragons with a fungal infection might display behavioral changes. They could be lethargic, have a reduced appetite, or show signs of discomfort when touched. Keep an eye out for these symptoms as they can be indicative of an underlying issue.

Though according to veterans reasons are not specific for white fungus infection, but still some of them included:

Poor Hygiene

A dirty or unhygienic environment is a common reason for white fungus in bearded dragons. If the enclosure is not cleaned regularly, harmful bacteria and fungi can thrive, leading to infections.

Humidity Issues

High humidity levels can create the perfect environment for fungal growth. Bearded dragons are native to arid regions and require a dry environment to stay healthy. Excessive humidity can weaken their immune system, making them susceptible to infections like white fungus.

Inadequate Ventilation

Poor ventilation in the enclosure can also contribute to fungal growth. Stagnant air and a buildup of moisture can create an ideal breeding ground for fungi, leading to infections in your bearded dragon.


Stress can weaken a bearded dragon’s immune system and make them more susceptible to infections, including white fungus. Common stressors include an overcrowded enclosure, improper temperatures, or a lack of hiding spots.

Remedies and Prevention of White Fungus in Bearded Dragons

Proper Cleaning and Disinfection

Regularly clean and disinfect your bearded dragon’s enclosure to prevent the growth of harmful fungi. Remove waste daily and perform a thorough cleaning at least once a week. Use a reptile-safe disinfectant to eliminate any remaining bacteria or fungi.

Controlling Humidity

Monitor the humidity levels in your bearded dragon’s enclosure using a hygrometer. Aim to maintain a humidity level between 30% and 40% for optimal health. If the humidity is too high, consider using a dehumidifier or ventilation to lower it. Alternatively, you can also reduce the amount of water in the enclosure or replace the substrate with one that doesn’t retain moisture.

Ensuring Good Ventilation

Provide proper ventilation in your bearded dragon’s enclosure to prevent the buildup of moisture and stagnant air. Make sure the enclosure has adequate air circulation, and consider using a mesh screen or vents to increase airflow.

Reducing Stress

Minimize stressors in your bearded dragon’s environment to help keep its immune system strong. Ensure that

  • The enclosure is the right size
  • Maintain appropriate temperatures
  • Provide hiding spots for your pet.

Also, avoid overcrowding and handle your bearded dragon gently to reduce stress.

When to Consult a Veterinarian

Bearded dragons with white fungus should be seen by a veterinarian who specializes in reptile care.

They can diagnose the issue and recommend appropriate treatment, which may include antifungal medications, topical creams, or, in severe cases, surgery.

Early intervention is crucial in preventing the spread of the infection and improving your bearded dragon’s chances of recovery.

Frequently Asked Questions

1. Can white fungus be contagious to other bearded dragons?

Yes, the white fungus can be contagious to other bearded dragons. If you have multiple reptiles, we would suggest you isolate the affected bearded dragon and sanitize the shared environment to prevent the spread of the fungus.

2. How can I tell the difference between white fungus and shed skin?

White fungus has a fuzzy, cotton-like appearance and may have an unpleasant smell. Shed skin, on the other hand, has a more uniform texture and doesn’t emit an odor. Additionally, white fungus may cause swelling or discoloration on the affected areas, while shed skin will not.

3. Can humans catch white fungus from bearded dragons?

It’s uncommon for humans to catch white fungus from bearded dragons, but it’s still important to practice good hygiene when handling your pet, especially if they have an infection. Wash your hands thoroughly before and after handling your bearded dragon to reduce the risk of transmitting infections.

4. Can white fungus be fatal to bearded dragons?

If left untreated, the white fungus can lead to extreme health issues and may be deadly to bearded dragons. Early detection and intervention are vital in stemming complications and improving your pet’s chances of recovery.

5. How long does it take for a bearded dragon to recover from white fungus?

The recovery time for a bearded dragon with white fungus can vary depending on the severity of the infection and the effectiveness of the treatment. With proper veterinary care, most bearded dragons can recover within a few weeks to a month. However, it’s essential to continue monitoring your pet for any signs of recurrence or complications.
