I've never been bitten by any of my axi's. They play with my finger and sit on my hand and chase me and stuff, but have never bitten me, and i hand feed them, they are pretty careful. It took me about 4 months before i would even put my hand in the tank, and that was why he was up the other end! It took me about another 2 months before I would put my hand anywhere near him, let alone TOUCH HIM!!! But now I have no problem!!!
