My spider has the bleached look on her neck circles, they have gotten lighter with sheds. I figured it was just normal for her. She doesn't have the change in color down her body though. No signs of infection and the skin looks normal, she is a pig and sheds out fine. Could it just be the pigment of your snake? Having said that I've only seen a few spiders in my time
Just to add could it possibly have anything to do with the het ghost?
I dont think its the het ghost showing because when i first got him he looked like any other spider. He has no infections and his scales look fine. Looks like its a mystery :p
