I was recently cleaning out Charlotte's tank and at the same time, cleaning her shell. She is only 4 months old and has never shed her scutes but I noticed that some were sunken. What is the cause of this? What can I do to fix it? She swims and basks regularly. Here is her feeding schedule if that helps:
[b]Feeding Schedule:
Monday - Sunday: Every morning gets 4 pellets and a veggie (usually romaine lettuce or the water lettuce from PetsMart).
Monday, Wednesday, Friday: Gets head sized piece of cuttlebone.
Now, my second question. I also noticed she has a tiny black spot on her head - near her ear. Thinking it might be dirt, I tried to take it off but it will not come off. Its not a raised spot but it's definitely not some kind of marking she has. There have been no changes in behaviour - she is healthy and as active as can be
Any advice would be helpful. Thanks Guys
* I've attempted taking pictures of both issues, but I can't seem to get a clear shot. I will continue to try, so I can maybe post a picture
