Huh? There are no freshwater sharks. They are all marine (salt water) animals. Several species can transiently tolerate freshwater for several hours, days or weeks, but none can live permanently in freshwater. If you want sharks, you gotta get a marine setup, and those aren't the easiest things to maintain properly. >>
I think I've read somewhere that there is one species of shark that is completely fresh water (lives in lakes, probably not your local one though so don't worry), but aren't very prominent. But you're absolutely right in that all the other one's are salt water fishies.
