Hello everyone, first post here so my apologies if this has been covered. I have a young 9 month old Redfoot, I bought him when he was around 5 months. His plastron has always had this weird texture and color, his terrarium is always between 75-90 in his basking area. Humidity is between 70-85, I have him on coco fiber as well, he does love to soak in his water as well. Any advice would be amazing, thank you!
