Hello, fellow Geordie

My Clown boy has one speckle like that on his belly and I swear I have to double-take every single time. But yeah, mites move and normally wedge themselves right in between the scales. You should be able to move them around by wiping them. Heat pits and chin are the more common areas but they can sit anywhere really.

What helped me was making a note of where the speckle was, and checking regularly to make sure it wasn't moving. After months of checking and seeing it hadn't moved, I put it down to definitely just being a single speckle haha.
