Thanks for reaching out about Lio and including photos. The pictures don't show any concerns except maybe some algae growing on the shell. This might be an indication of poor water quality. Test and correct water quality problems. For optimal growth, red eared sliders need to kept at a specific temperature range for optimal growth. Good luck.

Thanks for reaching out. The lesion on the neck is probably due to pulling the head in repeatedly and traumatizing the skin on the shell edge. Putting a visual blind around the tank might be less stressful. Not sure if the white is exposed bone, infection or hard water deposit. Can you gently scrub it off? The eyes on the first turtle appear a little swollen and this could be due to poor water quality or vitamin A deficiencies. What does the diet include? Check and correct water quality. Review diet. If lesion grows, a veterinary visit is recommended. Good luck.

This is no cause for concern at the moment. Turtles will routinely shed scutes (parts of the shell) as well as skin. Monitor for redness, lethargy, bleeding or any discharge. These are symptoms that should be addressed by your vet or a vet experienced in treating reptiles. Maintain pristine water quality via filtration and regular partial water changes. Many infections can be prevented by simply providing a clean tank.

The white spots may be due to high mineral content in your water. Salt from water softening systems may also be responsible. If you are feeding a varied diet (commercial sticks or pellets, live prey/protein, plant matter), maintaining water quality and proving adequate UVB light then there is likely no cause for concern. Monitor your turtles for soft shells, pitting, bleeding, redness, lethargy or decreased appetite.
