South FL Katie said:Its hard to tell from the pictures but his shell does look weird. I keep flip flopping about whether to just go get him and rehome him later but I'm worried about Cody catching something if it happens to be sick.
You should definitely keep him in a different room and wash in-between them, if you do get him! (But I'm sure you knew that)
I think the chances of Cody catching anything are slim if you're careful.
Good luck!
