Hello! I’m very excited to have adopted two red foot tortoises, Nazboo and Banana. They are very cute and outgoing guys. I’ve had then for about a week but I have noticed their plastron is very wrinkly and it does not look like she’ll rot as it is dry. I’ve look at the threads here but they don’t really look like this. Can it be fungal or perhaps this will go away as they age? Any help would be great
