Reptiles/Crested Gecko



My female crested gecko just lost her tail, shes turned really dark and seems a little hostile. I have a male crested gecko with her in the same cage and hes a little agressive. Any idea of what could have caused this? Also I have cardboard and papertowel in the cage could these things harm them?

Hello Stephen,

I apologize, this question must have missed my email!  Sorry about that.
Do you have a picture of your set up I could see?
How old are they, is he trying to mate with her & that is why she lost her tail?

If he is overly aggressive, that is most likely why she lost her tail, as it scared her.  If he continues to be aggressive, you may need to separate them so she can recover.
Are they both eating right now?

How is her tail doing, has it started to regenerate any yet?  
Please review your tank setup such as the temperatures, food offered, as well as supplementation.

I can answer questions pertaining to health, UVB specifics, overall husbandry care & supplementation, analysis of blood test results, and behavioral problems & handling. I can answer questions pertaining to bearded dragons, leopard geckos, iguanas, uromastyx & ball pythons. I can answer adeno virus related questions in bearded dragons, & then specifically about the testing methods as well. I am beginning an Pogona Adeno Testing Society in 2008 which will help to begin to start some standardization within the bearded dragon colonies of the breeders who choose to test.


I have been working with bearded dragons for over 5 years now, as well as leopard geckos, too. I am currently doing rescues, as well. I hope to be able to educate people prior to them purchasing an exotic pet in order to avoid any health crisis with them.

I have a master's degree in sports medicine & physiology, & 1 year of vet tech schooling, & am currently working on a reptile certification through the Pet Industry Joint Advisory Council.
