almost 1 year old male iguana, very weak, dark-yellowish color. Don't know what to do. zoo worker suggested giving C vitamin and Calcium which I did but didn't work. help

Hello Katie,

I am sorry your iguana isn't doing well.  Do you have any pictures of him & his tank setup that you could post for me to see?
What type & brand of UVB lighting are you using, is it a tube bulb or a compact/coil light?
How old are the UVB lights?
How often do you give calcium supplementation for him & what type, is it powder or liquid?
Please run over your tank setup with me, such as the UVB lighting, the temperatures & what type of thermometer you use to measure the temperatures.  His diet is very important, so let me know what foods you feed him, as well.
How long has he not been doing well, or did it come on all of the sudden?

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.
