Uh I hate to tell you but you wont get bit by that T. Youll get haired to death though

, and only bit if you really really make them mad.
As a G. rosea is a New World T, they are hair flickers, and rub their abdomen and kick the hairs at you. They do it fast too, which all the hairs do is make youitch and burn for a min or two depending on the T. Old World on the other hand are biters, and not for a starter T. OBTs and Poces are a big no if you are just starting out, sorry if others feel diffrent, but thats the way I look at it.
Also what are you using for water and for substrate? Do not use cotton or a sponge in the water.
