My dragon Marty, his tail is a completely different color than the rest of his body. He can vary from brown and orange to gold and orange ( depending on his mood) but his tail always stays this mundane brown/grayish color. He also has a kink at the bottom of his tail ( I think Petsmart caught his tail in the cage at some point) is the coloration something I should be worried about?
It doesn't look harmful at all. The problematic signs on a tail are dark color along with shriveling or open wounds. The gray dull color/waxy consistency is pre-shed state in every case I've seen.
