Please tell what species you have or think you might have. Describe their appearance (body weight, color, patterns, size) or can you possibly post a pictures. What are you keeping them in?, how is the basking site and UV lighting arranged? What material are you using for substrate, Humidity box? Hide boxes and/or areas? Diet you have them on now? Do you know if they are CCB or Imports? Treated for parasites?
I will help you to get started and the Discussion Forum will bring up other keepers experiences for you to collect information and see what works for your animals.
