Yea that was my thread it was amazing how much that tick looked like a little scale. But if its on the belly on one of the ventral scales. If you shine a flashlight on the scale and its bright red or bright brown it could very well be a tick. I thought the same thing that its an impending shed. If you have any hides that are the half log kind sometimes they may carry a wayward tick. A picture of the scale would help since i know what to look for.
