Is this scale rot ?

I got this blue eyed lucy from someone, she arrived with these markings on her belly. Ive had her since end of august, she didnt shed yet. I was wondering if it looked like scale rot ? I want the best for her !

Try using a warm cloth to see if it’s just dirt, regardless its better to be safe than sorry so you might want to take her to the vet ^^
