let me start by saying that i dont own any fish that pack a punch. my thoughts on owning them are: these are defense mechanisms, and i dont think that the fish/ray will use them unless they feel threatened. most of the time if you stick your hand in the water, fish will swim away. i dont know if i would 'shoo' the fish away, but crimzy owns these fish and has much experience on me. i just think that it could unneccessarily stress the fish out. if the lionfish should get one over on ya, you're supposed to soak your hand/arm wherever the sting is, in water that is as hot as you can tolerate without causing a burn. (in case you didnt know)
