Tarantulas don't read books about themselves - you may end up with an evil ball of hellfire Chile Rose, or a Baboon spider that would rather spend an afternoon mincing about daintily instead of hissing and attacking everything that moves.
I totally agree with Lopéz. I have had two or three of the same breed (Chile Rose), and they were different in their demeanour, two out of the three didn’t seem to mid being picked up, but the third, flicked hairs every time you went near it. I ma not sure if it had anything to do with their early conditioning. I think the third was a lot older and wild caught, and so was not used to being held or approached. I have read articles on the subject of conditioning, but most of it is unsubstantiated. An American author of a very good book on Tarantulas (the name escapes me at the moment) believes he has made progress in training a Mexican Red leg to come for food when called.
BTW, I have read that Tarantuals will eat fish if they are dropped into them alive.
