Out of all my Antaresia, only one of my female Children's and my Female Anthill are the only ones who don't try to bite at all. With all the others, they draw blood every time lol I think with size they get a bit better, but my 60 gram male bit and wrapped in between my thumb and forefinger, and it didn't feel very nice! Honestly, I kinda like their attitude. It helps me stay used to having something bite me all the time, so I get desensitized to the striking/biting which makes working with my more willing to bite animals easier (coughcarpetpythonsandbigangryboacough).
Spotteds get a good bit bigger than Children's.
