none that i know but they could if they pull the teethHow many public aquariums have piranha touch pools?? Please feel free to post a link. I would love to see one.
Also, piranha have fixed teeth with blood vessles and nerve endings in them. Stingray barbs do not.
i feel the touch pools are wrong .
its just a way to pull in the public so much risk to the rays you dont know what kids have on there hands
