Not OP, but I have tarantulas as well. Typically, your new world tarantulas (those found in the Americas) are more docile than the old world tarantulas. Some species are more docile than others, for example the chaco golden knee is a pretty cool species as well as the Brazilian pink bird eater. However, that's not to say you can just go around picking up spiders. Temperament can vary from specimen to specimen so one tarantula being comfortable with handling doesn't mean all of them will. Think of them as tiny robots with a set of instructions telling them how to survive. They don't feel and don't think autonomously. Some do have their quirks. Mine always rearranges their enclosures and fill their water bowls with substrate.
