This is Tiffany, gender uncertain. My son took the train to Los Angeles with his Boy Scout troop and came home with a new friend. His leader warned us of this new development by texting my husband a photo of my son with his new friend and the comment "congratulations on your new grandchild".
It's not legal to sell aquatic turtles less than 6" shell diameter, but this little one was only 1". True to his typical self, my son never asked how large his new friend would grow. Tiffany is now 4" and will top out at 10-12". When fully grown, s/he will need a 100 gallon aquarium. We have no idea where we will put that in our house.
