Is this a color change or had it always been this way? Reddish color change can be an early sign of infection. Please make sure the environment is clean, the water temperature and quality is good, and that the ambient temperature is high enough. If the turtle is showing any other concerns such as decreased appetite or energy then my concern level increases as well. A visit to a veterinarian who cares for turtles is never a wrong decision if you are concerned. I hope this helps!

    Hello, thank you for your question. Discoloration of the shells could be suggestive of an infection or shell rot. I would recommend contacting a veterinarian so that they can be seen and to determine what is causing the infection. In some cases environmental adjustment is all that's needed. Hope this helps!

    This may be an indication of infection or injury. Ideally, they should be physically examined by your veterinarian or a vet experienced in treating reptiles to diagnose and treat any underlying condition. In the meantime, maintain pristine water quality via filtration and regular partial water changes. Remove any sharp rocks or furniture that could scrape the shell which would predispose them to infection. If there is a significant size difference between the two, consider housing them separately until the smaller one gets bigger.
