well the impression i got wasnt that he/she wanted to completely tame them.. just get them used to a person being close to them.. and actualy just so you know.. my adult female is completely tame.. i bought her tame from a petstore.. and no she doesnt have parasites... anyway.. she acts the same way out of the tank on my arm as she does in the tank.. no color variation/ heavy breathing.. mostly she will just relax on my shirt
