Possible mites?

[Lyssamichelle96]

I have had Bean for almost a year and he is perfectly healthy. I noticed a black spot by his vent that didnt come off in his bath. Of course then I got paranoid thinking its mites and started googling. He likes to run through his poop and get it everywhere and knock little pieces off his logs so when i clean his tank and there are like black specs I dont usually think much of it. I cleaned his tank today and there was a small piece of shed with a black spec in it. There aren't any other unusual spots on him anywhere that I could find. He sometimes gets white dust on him (that I read could be mite dust?) but he also likes to play in his food bowl which ususally has calcium powder in it. Do these look like mites or am I being paranoid? Thanks.

Hi there, that's not a mite, just a random speck of debris.
