Causes of Tail Rot

Other causes can include poor nutrition. If your crested gecko is malnourished, it will have a calcium deficiency.

Calcium is essential for cartilage growth and strong bones. This can cause the tail to become weak and prone to infection.

Another cause can be due to an incomplete shed. This can cut off the circulation to the tail.

Further tail rot can also be caused by blood clots that lodge in the tail, restricting blood flow, known as embolisms.

Not meeting the required temperatures can also cause tail rot. Hypothermia in the tail can result in infection and cause the tail to rot over time.


It’s important to note that your crested gecko will not be able to grow its tail back once treated for tail rot. This should not impact your gecko negatively, infect crested geckos without their tails are known as “frog butts”.

The first thing you must do if you suspect your gecko has tail rot is head to your vet. The vet will be able to diagnose the tail rot and determine if the tail can be saved.

Once diagnosed, your vet will either give your gecko antibiotics to fight the infection or recommend surgery to amputate the tail.


The good news is that if the vet prescribes antibiotics, you have caught the tail rot in time, and amputation isn’t required.

Ensure you keep your crested gecko hydrated while on antibiotics, this will help the kidneys process the medication a bit easier.


The thought of your small crested gecko undergoing surgery is a scary experience, but there are times where surgery is the only way to save your reptile pet.

Surgery is offered when the tail rot has progressed and it can reduce tail loss, by removing the infection before it spreads any further.

To ensure the best for your pet you can reduce the risk of tail rot by not housing two male crested geckos in the same enclosure, reducing the risk of fighting and injury.
