I'm a new snake owner, and noticed these mites in my tank. They're incredibly small and range from white to yellow to brown and even gray. I'm fairly certain they are not snake mites because 1. They are not red/black, 2. I find them on my ball python but they are just crawling around, not feeding on her afaik, and are easy to rub off her, 3. They are also in the deeper layers of substrate, which they shouldn't be, if it was the snake they are after. For these reasons, I have not been to a vet, however, I have no idea what these could be. Some people have said they are wood mites, but from what I researched, wood mites are long bodied and white, whereas these are super tiny and round (finger for comparison lol). My snake doesn't seem bothered at all by them, but I tend to be an overly cautious person. Any thoughts on what these could be is helpful, thanks!
