get used to it... it will happen again and again as long as you have snakes.
in my 13 years of keeping and breeding i've been tagged at least a few hundred times. however most were by babies with an attitude.
i've noticed that both of my dums get a very strong feeding response after dark and go after anything that moves. so i generally leave them alone if possible. whenever i do decide to fool with them i'll use a hook to keep their head away while i grab their tail and move them around for a couple seconds so they know i'm not food. after that they chill out and are as calm as can be.
