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.
