You're welcome. I should specify a bit, they can tolerate moisture/humidity more than a lot of other Brachys because they come from a more humid environment than a lot of the other species, still I think it's best to keep it simple with species like this that don't require extra moisture/humidity, and to save it for the ones that really do need it more. I feel like when I'm talking to someone who is relatively new to the hobby, it's best to keep things simple and straightforward, especially because I have to consider the fact that that person is likely still trying to grasp the basics of tarantula care, and there's no point in telling them something that may cause them to overthink or stress over something that really isn't that big a deal. Plus it helps for noobs browsing the web whom may stumble across this forum and read this. To me an "advanced" genus/species isn't just a tarantula that can be fast-moving or defensive and possibly have powerful venom, it also has to do with their keeping requirements and how easy/difficult they are to keep alive. Like I've said before, with a lot of species you can bend the rules a bit and tweak the conditions here and there. Some people fret too much over moisture/humidity and half the time it's with species that don't even need it, like Avics. Now while it is still possible to overdo it here as well, you should be more concerned with keeping substrate moist with something like a Lampropelma species or Theraphosa.Both of these are actually prone to having molting issues, and they tend to do poorly if not kept on moist substrate. There's a reason why Brachypelmas are one of the most commonly recommended beginner's species. It isn't just due to their docile nature and slow-movement (which B.vagans is actually one of the few Brachys that is not always that docile and are more prone to being very skittish sometimes even defensive), it also has to do with how simple and straightforward their care is, and the fact that they literally have no special demands when it comes to things like moisture, humidity, substrate depth, ventilation etc. If you can grasp the basics of tarantula keeping, you can keep pretty much any Brachypelma species, and you'll likely have little to no trouble with any of them.
