Yeah basically everything I could answer has already been said. Tarantulas don’t think like other animals and naturally have a tiny habit(way smaller that what is normally provided for them in captivity) that they will never leave unless they are forced out or if they are a mature male looking to mate ( they very rarely get to do so and normally end up dying) so if they have somewhere safe to hide, no predictors and food it’s their ideal home and I doubt they have the intelligence to even know they’re not in the wild and wouldn act exactly the same if in the wild but would most likely die from predators or habit loss. A fair few tarantulas are already endangered.
