I remember in the late 60's and/or early '70's a pet store inside of North Star Mall that had a piranha. I dont recall if it was for sell or not.
In many places one can wade across across the Rio Grande without even getting your knees wet - especially during the summer season..... I dont think piranhas would be taken seriously in those spots.
That pet store inside of North Star Mall that had a piranha happened to be in San Antonio - just to clarify.
