I was hit twice by lionfishes. First they do not go after your arm when you put it into the tank. You only get hit if you place your hand near it. The top fins are the one's that get you. I was out for two weeks the first time. My hand felt heated up.
I place my hand in hot water and rushed to the hospital, thank God he was small a larger one would of sent me right to hell!
My hand was without any feelings for two weeks.
The second time was from a dead one, yes a dead one. I took it out with a net not noticing a spine sticking out from the bottom of the net. This one inflated my hand like a small catcher's mit. 8O Any way the second one was worse then the first one,
but I'm still talking about it. Who knows maybe the third one will do me in.
I now have many of them over 10" and those will kill you 8O if you don't get to the hospital on time!
