Hi everyone.
I was handling my BP today and i noticed this odd-looking scale on his belly. Could this be the beginning of scale rot?
His humidity is around 40-50% and i use newspaper as his substrate.
Would a betadine soak help him or should I take him to the vet? If it is the former, what is the ratio of betadine to water?
His belly is a bit pink because I believe is his about to go into shed.

thanks in advance
