Freshwater sharks being released in your local lake!

youde be surprised what ive seen in the local canals down here miami. Besides 100s of oscars. I mean lots of unwanted pets gone to big. Including some plecos. Dont know how long a pet fish would last in a canal but people get rid of them that way. :mad2:
 
wonder what kind of sharks tell be using. As far as I know there is only one true species of fresh water shark. Although not a true fresh water shark bullsharks can tolerate fresh water for some time.
