Hey yall, I have a 3 month old sulcata and over the last few weeks I've noticed this slight indention on the rear of the shell. Does it look like anything to be concerned about? He/she is about 110 grams, eats a varied diet mainly of grass with an assortment of greens/weeds/flowers mixed in. He also gets mazuri standard and ls as well as zoomed grassland mix in varrying rates 3 days a week favoring the ls and grassland mix. As well as calcium w d3 3 times a week and a multivitamin once a week. His enclosure stays between 70-80% humidity 100 degree basking and a humid hide near 100%. Daily soaks and outside for 30 min to an hour 3 times a week. Has solid poops and loves to roam outside and in the tub. Acts fine but just like any new parent I worry about every little thing.
