Baby Musk turtle doesn't seem well.

Me and my partner bought a baby Musk turtle from a reputable retailer just over a week ago. I was concerned at the time as his skin appeared to be peeling, but my partner researched it and said it was normal shedding. Since then, his eyes seem to have swollen slightly and be whitish, and he is acting really sluggish, sleeping a lot and not moving very much when on his raft. Do you know what may be wrong???
