There are many different things that could be causing these symptoms. It is hard for me to say too much about it without a photo or examining him myself. 1. shell rot 2. fungal disease 3. shedding (normal or abnormal) 4. mineral deposits I suggest you take Flash to a reptile vet for an exam so you can get a diagnosis and the proper treatment.

She could be shedding scutes, which is normal or she may have an infection. You can monitor her for resolution or worsening of symptoms. If necessary, maintain pristine water quality via filtration and regular partial water changes. You can clean affected areas using a diluted Betadine or chlorhexidine (Hibiclens) solution and a soft bristled toothbrush. Allow for a one hour dry dock (out of the water) after each cleaning. Provide a balanced diet, UVB lighting and vitamin/mineral supplementation to promote shell health.

Thanks for reaching out about Shelly and including photos. Black edges around the perimeter of the scutes could be just growth rings, but also possible inflammation (a melanin process) due to nutritional deficiencies, something irritating in the water and even a possible infection. If the problem expands, a veterinary visit is recommended. Review diet and husbandry parameters such as water temperature, basking temperature, UVB exposure and water quality. Good luck.

Hi there, there are a few possibilities here which I will describe, unfortunately I can't be more precise without seeing them. Worst case scenario is that this could be an infection causing shell rot, but it is likely in the early stages if so. Usually the shell will feel soft and can be smelly. Alternatively it may be discolouration caused by something in the water such as dye or certain algaes. Usually discolouration will come away when rubbed with a cloth. I would suggest heading to a good reptile vet to be in the safe side as if it is shell rot it is much easier treated early. Best of luck!
