I dunno if it is, or if I'm seeing things that aren't there.
The other side doesnt have the tiny little yellow bit... and at really close inspection it looks to be between the scales.
Hes eating well, loving his baths, pooing once or twice a day. He is well hydrated, and temps are good so I have no idea. Hope you can see well enough from the pictures, look at the pics its on the left side near where my hand is but a little lower.
Hi there....it doesn't look like it to me. I can barely see any color difference, but if you're worried you can always apply Lotrimin or Monistat to the area as a precaution. That way you'll already be proactive in case something develops. But it looks fine to me from what I see.
