Are these scales anything to be worried about? African File Snake.

Well file snakes are a little keeled, no? I've only dealt with them a couple of times and can't seem to remember.

I'm with you on the idea it's not scale rot. The belly looks good. The scales don't look broken or infected. Honestly, it looks like brown substrate stuck in them from dirt. My guess is the dryness might be from not enough humidity.
