I used to own a pet store, been stung by lion fish (it really, really suxs), bitten by triggers, very large snakes, Nile monitors (they don't let go) numerous rats, mice, damn hamsters with nasty attitudes (these go to the big snakes shortly afterwards. LOL)ect, On my perosnal fish, worse one I ever had was a 12" pollini, he was just damn mean. Drew blood on me, my wife and 2 of my 3 children. I have a huge Bolengerochromis microleptus now I'm very careful with, I'm sure he could take off a finger. Nasty teeth. Ken
