Booker lives in the Library at our school. He is over 15 years old! His shell is looking gnarly. When he dries out his shell looks light white, and his belly looks like it is shedding multiple layers at once. Sometimes he sheds his skin a lot and it hangs off looking like a white fuzziness all around him when he swims. I tried to brush it off with the toothbrush (RIP toothbrush). His shell is pyramidal in spots. I don't know if that was from overfeeding in the library or in his years previous to coming here. I put him on a diet anyway. Now he gets about 5 reptomin every other day. We also give him dried fruit mix occasionally. He is not happy about the new diet, and gets very animated when anyone pays attention to him. I am worried it might not just be overfeeding. I would love to have advice, as he has become a beloved fixture of the media center.
