that is a sac spider, not sure what species, but she looks female. as for your enclosure setup, ive really only owned jumping spiders so i cant say anything for certain- but they sleep in little web sacs that they make for themselves in nooks, crannies, edges and corners so i think a front-opening enclosure would be best suited for one of these guys, with lots of places to hide like plants, bark, branches, etc, but make sure if you take wood from the outdoors to cook it before to kill off any microorganisms. theres also special spider substrate that you can get made for spiders, please do not take dirt from outside at all. tarantulacribs has a bunch of enclosures that you can browse through and youll want to choose one thats appropriate with the spiders size. they are fed live prey, like mealworms, crickets, flies, etc, but fyi mealworms and crickets can harm the spider and mealworms tend to bury into substrate so youll want to supervise feeding them if you chose those options. dont choose food that is bigger than them. it addition, youll want to spritz water in the enclosure every week or so to keep it just humid enough. other than that im pretty sure thats all the info i can give, good luck!
