Why Is My Bearded Dragon Turning Black? 13 Reasons

Nicole Cosgrove

Bearded dragons are growing in popularity as pets, thanks to their distinctive personality. They also have a longer lifespan than most pets – they can live up to 15 years!

It can be alarming to see your beardy turn black suddenly, especially if you are a first-time beardy owner. Here is everything you will need to know about the color change in beardies.

Bearded Dragons Change of Color & Turning Black

Bearded dragons are capable of partitioning color to specific parts of their bodies because they have chromatophores. Chromatophores are cells that contain pigments and reflect light that generates their eye and skin color when reacting to their surroundings.

The color transition might occur gradually as your bearded dragon grows. Therefore, nothing is worrisome about your lizard friend turning black, mostly if the change happens in months.

Apart from the age factor, your beardy can change color and turn black for multiple reasons, ranging from communication to camouflage. And, it can happen on a scale of seconds to minutes, depending on the trigger.

Is It Bad?

Bearded dragons can change their dorsal coloration to different shades in various body parts like the neck, head, tail, stomach, chest, back, stomach, or all over the body.  These changes are entirely normal and okay.

These remarkable abilities to change colors were made possible by breeders that selectively bred the beardies over many generations. The breeding efforts made it possible for reptile enthusiasts to choose their beardies in various colors and patterns.

Although color changes are expected with beardies, you should pay attention to the circumstances leading to the sudden transition. The reason for the color switch ranges from internal reasons to the animal’s surroundings. It is upon you to understand why a naturally-colored dragon can change to black.

Reasons Why Your Bearded Dragon is Turning Black

1. Temperature Regulation

Temperature change is the most common reason for a beardie to turn black. Since these reptiles thrive on high heat, darker shades help absorb heat faster than other colors.  So, when it gets cold and chilly, they turn their skin black to soak up and absorb as much heat as possible.

Having a black color on their backs reduces the time they take to reach their body temperature. Most dragons turn black more often in the morning and return to normal after basking for a couple of hours later in the day.

You can know if your pet is cold by measuring the temperature ranges in their enclosure. Ensure that adults’ basking enclosures range from 95-105 degrees Fahrenheit and 105-110 degrees Fahrenheit for baby beardies.

2. Feeling Threatened/ Scared

Beardies retaliate to threats or show fear by turning dark to warn the potential threat against attacking or messing with them. The threats could include other pets or your activities infringing in a beardies’ space. However, the color resolves as soon as it gets comfortable with its enclosure again.

For this reason, you should ensure your lizard friend is comfortable by providing a stable and safe environment. It might require you to exercise patience while handling them and keeping other pets away.

3. Stress

Your lizard friend can turn black as a way of letting out the stress within and projecting its feelings. Triggers of stress include relocation, birds, other pets messing with them, loud noises, or vibrations.

It would help if you calmed it down by removing the stressors. Without the stressors, the beardy can return to its usual color quickly.

4. Looking for a Mate

Male beardies have darker beards than the female. Therefore, it’ll show off this feature to attract females during the mating season and let them know it is a suitable mate.

A male beardy will also include head bobbing alongside its dark features to flirt with the females. However, this behavior only applies to those of at least half a year old. There’s not much you can do to stop your pet from changing color during this season because hormones are in control.

5. After Brumating

It’s not unusual to see your bearded dragon turn black after brumating smoothly. After brumation, adjusting to long hours of daylight and finding its appetite again after coming from a deep sleep affects its mood.

For this reason, the dragon can darken for days and weeks until it adjusts again. Please do not push it around too much. Instead, give it time to transition to their old selves.

6. Feeling Territorial

Darkening to show dominance isn’t so common unless you are keeping more than one beardy. If that’s the case, you’ll notice one of the pets, especially the male changing color to signal that it is now dominating over the space.

Your pet will accompany the coloration with other behaviors like head bobbing or lying on top of its rival when marking its territory. Keeping two dragons in the same space isn’t a good idea because these dragons are solitary creatures. You risk terrible fights over territory or sexual harassment of the females by the males.

7. Feeling Aggressive

Just like a human’s face can turn red due to anger, a beardy turns black to show it is mad or annoyed. It usually occurs during upsetting baths or when it’s around other pets.

This color-change is a signal that you need to remedy the situation. If a pet is making it mad, keep it far away from your dragon. And if it is the bath, well, don’t bathe them regularly.

Instead, mist it or give it water droplets on its snout for it to lick. Only bathe it during shedding.

8. Feeling Unwell or Sick

This is the reason why you should always be on the lookout to notice when your lizard friend darkens. A bearded dragon can turn all black or develop circular stress marks when battling severe illnesses.

Other accompanying signs like lack of appetite, reduced movement, or swollen belly indicate that your dragon is unwell. Take your pet to a vet as soon as you see these signs alongside the black color.

9. It Is Not Comfortable Around You

If you adopted a beardie recently, it might take time for it to warm up to you. For this reason, your beardy can turn black until the day it’ll start trusting and getting comfortable around you.

The best approach is to give it time and space to get used to you. If you rush the bonding and interact with it before it adjusts, the chances are that it’ll turn black.

10. Loneliness

Beardies are smart! If a lonely beardy wants your attention or a chance to play outdoors, it’ll decide to grab it by turning its neck black. If it does this when you let it down in its habitat or after you ignore it for a while, the little guy wants your attention so bad. If you suspect that is the reason your beardy is changing color, maybe it’s time to let it out of its tank and cuddle it a bit.

11. Poor General Care

A bearded dragon can sometimes darken because of the small miscellaneous activities around it. For instance, a low diet, dingy habitat, or inadequate lighting can upset your lizard friend. If you discover changes with your little buddy, evaluate your care plan and fix where necessary.

12. New Environment

The entire process of relocating and settling in a new environment seems overwhelming for bearded dragons. The loss of a place they knew as home, new people, and a new enclosure can make them feel insecure and set-in anxiety and fear.

The fear and doubts can make them turn black as a way of showing their feelings. The only thing you can do for your lizard friend is to give it space and time to acclimatize. The black color will go away as soon as it starts feeling comfortable.

13. Poor Lighting

Unfortunately, most beardie owners do not understand how much lighting bearded dragons require. And, the misleading information on the internet does not help.

Bearded dragons need enough illumination to stay healthy. You should know that white UV lights are the most suitable for beardies. These lights help build their appetite and improve their mental well-being. To ensure enough lighting, use the correct UVB bulbs, and replace them after every six months.

Although color transformation on beardies is not a cause for alarm, a loving beardy parent will try to understand why his pet is turning black. To achieve this, observe and maintain your pet’s surroundings.

Beardies’ general rule of thumb demands that you look at each situation independently since some cases might require medical attention. Plus, a color change should happen only once in a while and settle down fast.

Take action if it takes ages to resolve and if your beardy turns black more often than usual. The bottom line about keeping a bearded dragon is keeping it happy and comfortable!
