Yeah, they'll sink, rumour has it they'll turtle a while but unless they've been altered dramatically they'll sink under the wrong conditions. I think several of the guys have had the experience and others have come to their rescue. Here's an old post. And they will sink in freshwater faster as I think saltwater offers more bouyancy.
