All have the chance to be aggressive at some point or another.. hungry, or react defensively if startled. There are many that are known to generally be 'nicer' than others, but this is not always the case. I'd recommend a Brachypelma sp. or a Grammastola pulchripes, a hundred times over a rosehair... not only for a more consistent temperament, but you're also less likely to go on a fast, or have problems because of being more sensetive to their environment. I would never approach a spider like the person did in the video unless I'm TRYING to get a bite... soft barely noticeable movements near the front of the body? What do you think crickets feel like when they approach a spider? I don't offer a horse a carrot by holding it between my fingers, I don't stick my fingertip out to a rat (especially one guarding babies), and I don't let my hand crawl around like a mouse in a snake's cage.
There are safER ways to approach and handle a tarantula, but there are never any guarantees, and frankly, most of them don't particularly enjoy being handled... some just seem to tolerate it better than others. Unless a person is aware and OK with the idea that they might get bit, it's probably not a great idea to handle them at all with hands![]()
