Thanks for reaching out about Zero and including photos. Is the shell soft and easy to indent? If so, a calcium deficiency is likely. This could be due to dietary deficiency or lack of ultraviolet radiation, needed to convert vitamin D3 to an active form. Vitamin D3 is needed to absorb calcium in the intestinal tract. A veterinary visit is recommended to assess healthy and prescribe treatments.Check and correct water quality parameters. Good luck.
