according to AMS (piranha expert) the red bellys would run away from your arm, as long as you aren't bleeding, so, they aren't going to kill you lol
I agree with demonmagus, they will more than likely hide away just like any other fish would, just make sure you arent bleeding![]()


My Gourami will touch my arm with his feelers and nibble at my fingers the entire time my hand is in the tank.![]()
