I have a male veiled chameleon with a small area on the ridge of his spine that is white and dry. It looks like it is starting to crack (much like someone with very dry, cracked hands).Though at first I thought it was just shed but it seems to have progressed and in that area the ridge on his back has smoothed out. He is otherwise very healthy but I am concerned it might progress. Does this sound fungal? Thanks for the help.
