IT IS A REALLY BAD IDEA FOR ANYONE TO BE FEEDING SHARKS EXCEPT IN CAPTIVITY!!!!!!!!!!! THIS IS GOING TO GET PEOPLE HURT OR KILLED!!!!!!!!!!!!! Lionfish are one of the best tasting fish in the sea if you goto the trouble to kill them you should eat them or at the very least bring them to the surface to properly dispose of them. Feeding sharks only teaches them that divers offer free meals!!!!!!!
