All I have is a red slider turtle. And he's a really fussy eater; won't eat anything else except fake crab meat and the turtle food that the local Kmart sells. I pour that turtle food into his tank and he's on it like butter on bread!
I wanna see this turtle! Post a photo! :) I hear they're quite common pets in the USA (and I've seen wild ones swimming about in ponds and things), but in the UK they're almost unheard of. So a total novelty for me! XD
I'll try to borrow a digital camera so I can take a pic of him next time I clean his tank. You probably won't see his head out much when he's not in his tank, though; he tends to "stay in his shell" when out of the tank.
And then there's that Italian plumber I have to watch out for; he likes stepping/stomping on turtles. :(
