Of those four I have personal experience only with g. rosea.. I've had mine 3 years.. it's never kicked hairs, and I used to handle it (I prefer to leave them alone now) it never tried to bite, but if you breathe on them they freak out.. be careful they're very fragile animals.

My friend has G. pulchra.. gorgeous spider, and they are known for being docile.

B. smithi is known for it's great pet qualities. Truly beautiful spider too.
