fly river turtle frt

Hey, I adopted a FRT 15 days ago. Then I relised some wounds on his bottom shell and brown spots on her nape. I cannot capture spots on nape it but bottom is; General tank setup; there is a wound on her nape seems brown not like gray own her normal skin. BTW I started to use UV on filter...

Here's some Juvenile Fly River Turtles for your viewing pleasure. They're just at the age where they're finding out how much they hate each other.
