Yellow belly slider shell changing color? Is it shell rot or shedding?

Updated On September 23rd, 2025

Hi, I am curious as to why my yellow belly slider's shell seems to be changing colour. I am not sure if it is shedding, or is a sign of shell-rot. Also, it's skin seems to be slightly whitish in colour. Do you have any diagnosis and solution to this possible issue? Thanks!

By the images, it doesn't appear to be shell rot. This cannot be determined definitively though without a physical exam. The will shed skin from time to time, so this could be what is happening. Hard water deposits may also change shell color as will age. Maintain pristine water quality, provide ample UVB lighting and feed a balanced diet. All these will promote shell health. You can review slider care at the link below. (Yes, it is titled 'red eared slider', however RES and YBS care is identical). http://www.anapsid.org/reslider.html
