I noticed about a week ago that my ball python had a new brown mark by his neck on his underside and I started to worry it was scale rot. I had him on coconut fibers but then immediately switched it to newspapers to lower the humidity. My thermometers recently broke and I ordered new ones on Amazon, but COVID-19 is making it difficult to receive them quickly. I also ordered new cypress mulch instead of coconut fibers that will get here on Saturday. I have been applying Vetericyn plus on the affected area for two days now and it seems to have gotten better, but not disappeared.
