Are black dots on my red-eared slider's shell normal after shedding?

Looks can be deceiving, but the shell looks fine in the picture provided. "Heathy" is more than just a clean shell though. He should be eating and defecating normally, basking regularly and swimming. There should be no redness or pitting on the shell. Provide clean water at proper temp, a basking spot also at proper temp, UVB lighting and an appropriate diet. You can review the article at the link below to confirm correct husbandry. http://www.anapsid.org/reslider.html

It could be some minor shell rot. Use a soft bristled toothbrush and some diluted betadine or chlorhexidine (Hibiclens) to scrub the affected area once or twice daily. Allow for a 1 hour dry dock (out of the water) after each cleaning. Maintain pristine water quality via filtration and regular partial water changes. If the spots do not resolve or if they spread, have Squirtle physically examined by your veterinarian or a vet experienced in treating reptiles. A UVB light source, calcium powder and multivitamin will promote shell health. You can also float a piece of cuttlebone in the tank for him to munch on as needed. It will provide additional calcium. Find the cuttlebone in the Bird section of the local Petco. The link below will provide additional information regarding the care of sliders. http://www.anapsid.org/reslider.html

If you have exceptionally "hard" water, it could be calcium deposits, but you would likely have noticed it prior to or during the transfer. Have the water tested to be sure. Dry dock them for 2-3 hours a day for the next few days and see if that makes a difference. You can use a soft bristled brush and some diluted chlorhexidine (Hibiclens) to gently scrub the shells before dry docking. Continue to monitor for lethargy, decreased appetite and softness or pitting on the shells. See your veterinarian or a vet experienced in treating reptiles for a physical exam if necessary.

UVB lighting is critical to shell and overall health. If you don't yet have a UVB light source, you can take Jazzy outside in full sun for at least 60 minutes daily. Use caution to prevent overheating though. Perform a partial water change (30% total volume) and scrub and tank furniture. Confirm the filter is rated for at least twice the volume of the tank. You will likely need to perform partial water changes weekly or every 2 weeks to maintain water quality. Turtles eat and defecate in the water, so it can get dirty very quickly without regular maintenance. Scrub Jazzy using a soft bristled toothbrush and a diluted Betadine or chlorhexidine (Hibiclens) solution. Allow for a 1-2 hour dry dock (out of the water) after each scrubbing. Monitor for lethargy, loss of appetite, soft spots on the shell or pitting. These are symptoms that should be addressed by your veterinarian or a vet experienced in treating reptiles.

Thanks for reaching out about Kelby and including photos. Can you gently scratch the white areas with your fingernail? Is so, probably mineral accumulations from the water and not a problem. If not, this could be keratin erosion from sub-standard water quality, infections, too cold of an environment. A veterinary visit would be recommended. Good luck.

The rubbing is done to aid in shedding scutes. The digging and pushing may also be attempts to aid shedding. Inspect the shell for soft spots, pitting or fungus. Confirm proper environmental conditions (water quality/temp, ambient/basking temps, dry dock, UVB lighting) as well as proper nutrition.

Thanks for reaching out about Squirt and including a photo. The two most common causes of this are mineral accumulations with hard water and exposed bone. Mineral accumulations you should be able to scratch off with a fingernail. Water source might need to be changed to filtered water or commercially available spring water. Exposed bone is usually due to poor water quality (high bacterial or algal loads) that erode the keratin layer. Water changes need to be made more often, but a veterinary visit is recommended as systemic antibiotics might be required. Good luck.
