Hi this is my 5 year old map turtle. I'm not sure if this is she'll rot or not. She is acting perfectly normal and doesn't seem I'll at all. I've been feeding her a varied diet of dried shrimp, dried fish, pellets and frozen prawns. She has good space to get out and bask which she spends alot of the day on. I cannot understand how she would have got shell rot as she is always out basking.
