Crested geckos are beautiful creatures with different colors and patterns. But sometimes, you may notice some black spots on your crested gecko.

Naturally, that can leave you confused as to whether it is part of a pattern or morph, or is something to worry about.

What Are The Black Spots On Your Crested Gecko?

The spots on your crested gecko can either be due to the changes in morph patterns that occur as your crested gecko ages, or they can sometimes be mites.

It is common to see sudden changes in the morphs of your crested gecko – they may develop or lose their spots and stripes as they age.

It is virtually impossible to tell what pattern your crested gecko will have permanently when it is first born.

While stripes on a crested gecko do not cause any confusion, the appearance of spots may indicate mites too.

So, it is important to understand whether the spots on your crested gecko are part of the changing morph or mites.

Is A Black Spot A Symptom Of Bad Health Of Crested Gecko?

If black spots can also simply mean a natural change in morphs, then how can you be sure if the appearance of black spots is a matter of concern or not?

The key is to observe the other behavioral changes that accompany the appearance of black spots.

In crested geckos, as with any other living being, a health problem comes with a bunch of common signs and symptoms.

So, if the appearance of black spots on your crested gecko is making you concerned, try to look out for one or more of the following signs:

  • Lethargy
  • Restlessness
  • Dehydration
  • Loss of appetite
  • Weakness
  • Visible injuries
  • Imbalances in the enclosure environment

If you notice these signs along with the black spots, chances are that your crested gecko is unwell.

But, if you simply see some black spots on the skin of your crested gecko, and there is no change in the overall behavior of your crested gecko, it is most likely just fine. You then have nothing to worry about.

Are The Black Spots Patterns On The Crested Gecko?

It is very likely that the black spots on your crested gecko are simply new patterns evolving as your crested gecko grows in age.

This is the likeliest reason behind the sudden occurrence of black spots on your crested gecko if you’ve had it since it was a baby and now it is growing into adulthood.

However, be wary of the black spots that appear overnight. These are generally the signs of mites.

The black spots that come as part of a new morph are slow and increase gradually in number. Mites, on the other hand, reproduce very quickly.

How To Tell If You Have A “Dalmatian” Gecko

The dalmatian gecko is a very interesting morph in the species.

A crested gecko with a morph pattern of black, brown, or red spots is often called a dalmatian gecko.

Some signs that show that you may have a dalmatian gecko are:

If you want to be sure, you can always ask your breeder or pet shop.

The information from a pet shop may not be that reliable, which is why it is recommended that you always get your crested gecko from a reputed professional breeder only.

Why The Black Spots Called Dalmatian Spots On Crested Geckos?

The name “Dalmatian” comes from the breed of dalmatian dogs. Dalmatian dogs are known for their unique coat of white fur and black spots.

So, when breeders came across this morph of crested geckos that had a similar pattern of spots, the name dalmatian was attached to this morph.

What Does It Mean If Your Crested Gecko Has Black Pores?

Black pores or black spots on your crested gecko are most likely just dalmatian spots.

Unless you see a raised spot, that is coming out of the skin, much like a boil or a pimple, you don’t have to worry about it.

Patterning and changes in morph are common in crested geckos as they age.

When they’re growing, if they carry the active gene for dalmatian spots, you will observe more and more black spots as they shed each time.

Do Black Spots Make Your Crested Gecko Look Pale And Dark?

No, the black spots on your crested gecko do not make it look pale and dark.

They are tiny dots that cover the body of the crested gecko much like stripes.

However, there can be other reasons for the pale appearance of your crested gecko. Some of them include:

  • Shedding
  • Aging
  • Naturally pale base color
  • Fired down or relaxed state

So, if your crested gecko is looking pale, first check the environmental parameters or it might be shedding.

If everything is all right on your end, then chances are your crested gecko is about to start shedding soon.

The black spots do not make your crested gecko look paler.

Do Black Spots Cause Physical Problems?

When the black spots are a part of the changing pattern of your crested gecko, they will not cause any physical problems.

It is just the morph pattern of your crested gecko that will keep getting developed after each shedding cycle.

If, however, the black spots are mites, you need to act fast.

They won’t just cause a physical problem – they are the physical problem!

Mites reproduce really fast and will take over the entire enclosure overnight if you don’t act fast.

Can There Be Black Spots On The Crested Gecko Due To Burns?

Yes, black spots can sometimes be a sign of thermal burns. You need to check the temperature of the warmest and coolest sides of your crested gecko tank.

If there is a very hot heating lamp inside the tank, chances are that it may have heated up the nearby walls so much that when your crested gecko accidentally touched it, it may have gotten a thermal burn.

In case of a thermal burn, your crested gecko should also appear to be lethargic.

Moreover, in this case, the black spots will be concentrated toward the region that came in contact with the hot surface.

The spots won’t be uniformly distributed all over the body, as is the case with patterning. If that is the case, you should immediately contact your vet.

Can Fungal Infection Cause A Black Spot On The Crested Gecko?

Yes, even a fungal infection can sometimes be the reason behind black spots on your crested gecko.

A crested gecko tank is a high-humidity environment.

When the moisture levels are high consistently, you need to ensure that hygiene is maintained.

Else, the environment becomes a breeding ground for fungi and bacteria.

One such fungus, called the yellow fungus, can often cause skin infections in crested geckos.

This skin infection can show up as black spots all over the body of your crested gecko.

This infection is again going to be accompanied by symptoms like lethargy and loss of appetite.

Can You Treat Your Crested Gecko When It Has Black Spots?

If the black spots on your crested gecko are simply patterns, you don’t need to treat them at all.

However, if these are caused by mites, fungal infections, bacterial infections, or thermal burns, you will need to treat them.

Take your crested gecko to the vet. Revamp and deep clean the enclosure of your crested gecko.

Give proper treatment and follow the prescriptions. Once the root cause gets cured, the black spots will also disappear.

When Do These Black Spots Arrive On The Crested Gecko?

Black spots that appear due to natural patterning come gradually. Their quantity increases slowly after each shedding cycle.

However, if the black spots are due to medical conditions or injuries, they will appear overnight.

The duration within which the black spots appear on your crested gecko serves as the first hint as to whether or not you should be concerned.

If today your crested gecko has absolutely no black spots, and tomorrow suddenly your crested gecko is filled with them, something is wrong.

Can The Black Spots Be Of Different Sizes?

While the sizes of black spots that come as a pattern vary from one crested gecko to another, on a single crested gecko, the spots will be more or less of the same size.

They might not be of the exact same size – but they won’t be drastically different in size either.

Do Crested Geckos Change Colors?

Yes, crested geckos change colors. They change colors as they age. They also change colors when they are fired up or fired down.

They become paler when they are about to shed. They regain a bright, vibrant color after shedding.

Crested geckos become bright or very dark when fired up. They become duller when they are relaxed.

In fact, not just the color, but the pattern on the morph of a crested gecko also changes as it goes from babyhood to adulthood.

That is why you can never tell the “original” morph of a crested gecko when it is still a baby – because nobody knows what morph it will grow into and settle into once it becomes an adult.

How To Tell If Black Spots Are Mites?

An important thing to know is how to distinguish between black spots of a natural pattern and black spots of mites.

The simplest way is to observe two things:

  1. Did the spots appear overnight?
    If the spots appeared overnight, chances are that these are mites. Dalmatian spots appear gradually after every shedding cycle.
  2. Are the spots coming out of the body?
    Dalmatian spots will be like painted ink blots. They will remain on the surface of the skin. They won’t protrude outside like 3-D figures. If they are coming out in 3D, then they’re not patterns. They are mites.

How To Get Rid Of The Mites

The best technique to get rid of mites on an infected crested gecko is to give it a Betadine bath that has been diluted with water, then use warm, wet cotton swabs to carefully wipe the mites away from the gecko’s eyes, mouth, vent, and other sensitive regions.

You can also use commercial mite sprays that are available in the market.

But if you don’t have one handy, and your crested gecko is already infected, you need to immediately give it the Betadine bath.

Summary

Any changes in or on the crested gecko become a natural cause of either confusion, concern, or both for the pet owner.

The same goes for the occurrence of black spots on crested geckos.

While there is no reason to worry about a gradual appearance of black spots on your crested gecko, a sudden overnight occurrence could mean health issues or burn injuries.
