Iguana Tail Turning Black - Reasons and Tips for Tail Rot (2023)

Iguanas have long, beautiful tails, but various problems can cause tail rot and death. In this post, we will discuss the reasons why the iguana's tail turns black, as well as the reasons why the tail rots and tips on how to deal with these problems.

First, let's look at the signs and reasons why your iguana's tail might be turning black. And then we will discuss what you can do in such cases.

Signs of tail rot in iguanas

  • The tail part turns brown or black.
  • dryness
  • Loss of feeling in the damaged part of the tail.
  • The damaged part of the tail can easily break.
  • The tail can look and feel like leather and be stiff.

Do not confuse a necrotic (dying) blacktail with a fungal infection of the skin. The skin fungal infection shows brown/black patches and the affected areas are usually in different places.

Why is my iguana's tail dying?

1. Your iguana flapped its tail hard.

Your iguana may hit the object (such as the sides of the cage or accessories) very hard with its tail. The same can happen if your iguana wags its tail when it becomes aggressive towards you or is in a bad mood. Its tail can also get caught between doors, under lights, etc.

Accidents are also common when iguanas bump into various objects during the breeding season. This leads to reduced blood flow, causing the tail to become hard and brown. If the tail has turned brown, it is tail necrosis - tail death.

2. The restrained spill caused the blood supply to the tail to be cut off.

Iguanas molt every 3-4 weeks, but babies and juveniles molt more frequently. Sometimes iguanas drop sticks on their tails, toes, and around their heads. It is very important to spray your iguana twice a day and to bathe it regularly (every day or at least 4 times a week).

Iguanas need plenty of moisture in the tank to shed properly. If your iguana kept the scale, it will gather in the tail. Even a few layers of skin can build up if you don't help remove them.

The accumulation of fur impairs blood circulation, causing the tail part to turn black. This leads to dry tail rot or dry gangrene.

3. Your iguana fell off a tall structure.

This also happens more often than you might think. Iguanas love to climb and will often leap off tall structures without much care. Your iguana should have a vertical cage, but make sure it can get in and out safely. Falling from a tall structure can injure your iguana's tail, toes, and limbs.

4. There is an abscess on the tail.

Your iguana's tail can become infected from the inside, causing a cyst or tail abscess to form. You can tell it's the cyst/abscess if the tail has a lump. The abscess can form after an open wound on the tail as the infection spreads.

If you leave the cyst/abscess untreated for a period of time, the blood supply to the tail will be compromised, resulting in a necrotic tail in your iguana. The necrotic tail must be cut off.

Any cyst/abscess should be punctured and the pus washed out. You must keep the wound clean until it heals.

5. Iguana bites its own tail

If your iguana is biting its own tail, it means something is wrong with your iguana. It might be okay if your iguana just nibbles - the tail might be itchy or about to fall off.

But when it bites properly and causes injury, there is a problem. Your iguana may bite its tail if something hurts. The tail may be itchy due to infection or mites.

Your iguana can also be highly stressed: males may bite their tails during breeding season and females during oviposition.

  • If the tip of the tail is injured and turns black, it may fall off on its own. However, it is not good to wait for it as it will continue to spread. The dry stain must be removed. If the black part of the tail falls off, you can help remove it by snapping it off at the break point. Make sure it is dry and pliable before doing this.
  • However, when most of the tail is injured, it begins to darken. This is ischemic gangrene (blood circulation has stopped). To prevent gangrene from spreading, you need to take your iguana to the vet, who will do itAmputate the dying part of the tail.
  • Note that the tail should be slightly docked.Overdead tissue (1-2 mm higher). Because if you just amputate the dead tissue, the infection will likely spread back down the tail.
  • Do not trycutnecrotic tail itself - it's painful for your iguana. If you can't visit the vet, the only option is to break the blacktail tip and disinfect the wound to help it heal. Pruning at home is very risky and will be very painful for your iguana.
  • Breaking up dead tissue can be easier than cutting: the tail has breakage points.
  • If an abscess or cyst is present, it will need to be cut open to remove pus and washed with antibiotics.

How to treat and disinfect the tail wound?

  • If your iguana has broken its tail, in some cases you can still save it. Wash the wound (if any) with an antiseptic, but never use solutions containing alcohol, as they can cause severe burns.
  • Chlorhexidine is one of the pet disinfectants. After that, attach a stick or something else that will serve as a splint. Secure the splint and cover it with a bandage.
  • The broken tail that is saved often grows wrong and crooked. At this point, it's just aesthetics.
  • Always take your iguana to the vet, who will perform the amputation or removal of the cyst under sterile conditions.. Sometimes the vet will administer anesthesia, especially if the tail needs to be docked.
