Scale rot? HELP :(

[Kimberly_H]

My blue came to me with what looked like a burn on him, and now its spread to all over him, i have a vet appointment but they can't see him until Sept 12th
I'm literally freaking out.
Is this scale rot? Something else?
Humidity is around 75% basking spot is around 120 and cool side in 80s

My male has a couple spots like that, and I increased his fish oil. It hasn't changed yet, but I just wondered if you give him fish oil at all, and/or what you feed. Seems like it's something missing in their diet, but I don't know for sure. Btw - cool side is actually supposed to be in the mid-low 70's. Otherwise, your bask, and humidity look good as long as he's an adult. Young Tegus should only have around 110 as a basking spot.
