Can anyone tell me what this could be? I noticed my beardies scales look a darker than normal a couple weeks ago but I thought it was because i just switched her bedding to sand (i switched back to carpet). she now has a patch under her tail and dark spots. She’s eating and pooping normally and has a intense uv bulb and her basking spot is about 98 degrees
That isn't scale rot, but, either a combination of an upcoming shed & dirty scales from the sand.
You can give daily baths for awhile, using a small soft toothbrush to gently scrub the scales
clean.
I agree, it's just dirty stained shed. It will come off.
Sometimes they get like that of they run through a loose stool or sit in wet sand like Tracie mentioned.
