My baby turtle has a black spot on its shell. What should I do?

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.

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

The peeling scutes may be normal shedding. Do not attempt to remove them yourself. Maintain pristine water quality. You can use a soft bristled tooth brush and a diluted Betadine solution to gently scrub the shell or affected areas. Allow for a 1 hour dry dock (out of the water) after each cleaning. If the UVB bulb has been in use longer than 6 months, replace it. Make sure it is not blocked by fine mesh, glass or plexiglass. Provide a balanced diet including prey, fresh greens and vegetables and a commercial pelleted diet. Dust food and prey with both a multivitamin and a calcium supplement regularly.

Shell rot is characterized by pitting, soft spots, foul odor or discharge or loss of scutes. It can be a serious condition and requires veterinary attention. Your turtle may have rot or the discoloration may be due to excess mold or algae. Clean the tank, do a water change and change the filter media. Confirm proper environmental conditions for your particular species of turtle. Try using a toothbrush and gently scrubbing the affected area of the shell. Make sure your turtle has a warm, dry basking area with proper UVB lighting. If your UVB bulb is older than 6 months, replace it. Do not place glass or plastic covers between the turtle and the UVB bulb. Feed an appropriate diet and dust food with a calcium supplement once a week.

This could be a fungal or bacterial infection. You can try to manage it at home by maintaining pristine water quality via filtration and regular partial water changes. Make sure any filter you have is rated for at least twice the volume of the tank. Remove any uneaten food promptly to prevent it from fouling the water. Use a soft bristled brush and a diluted betadine or chlorhexidine solution to gently scrub the affected areas daily. Keep the turtle out of the water fro an hour or two after each cleaning. If the spots do not begin to resolve within 5-7 days, you may need to seek veterinary attention.

Yes, the images are blurry. The best you can do is monitor the spot for rapid change or growth. Maintain water quality and environmental parameters. Provide a well balanced diet along with vitamin and mineral supplementation. Unfortunately, without a physical exam, there is not much more to be done that you aren't doing already.

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.
