Poec! You're back!"I am going to say that "aggressive" OBT's are due to husbandry."
This statement is false. They defensive because of predation, competition, and other factors of their native habitat. It's reinforced/rewarded behavior from many thousands of years of evolution. Africa has many ruthless predators that eat tarantulas: mongeese, honey badgers, baboons, etc. The strategies that are successful most often for OW tarantulas are: 1) running at top speed in an unpredictable direction, 2) remaining motionless and exploding in a fast run if touched, & 3) instantly becoming defensive and employing their relatively strong venom if the warning doesn't work. Without urticating hairs, they can't throw projectiles from a safe distance like most NW terrestrials can. There is variation within any tarantula species, with most doing what works the majority of the time, and a small number trying something different. This is the key to evolution for all living things, that allows them to adapt to changes in their habitat.
Having gotten my first tarantula over 40 years ago, I've owned and worked with many hundreds of tarantulas, both w/c and captive bred, and have seen no pattern in defensiveness being higher in one group than the other, in any species. Instinct drives their responses.
I can't comment at all on making OBTs and their defensiveness, the closest thing I own to one is a C. darlingi or a C. vonwirthi. What I would like to ask OP is why you want a super mean defensive one?
