I would move her onto coco fibre as there is no need for her to be on vermiculite as she does not need additional humidity. Also u may find that she will burrow once she has coco fibre. Also u may need to put more substrate in than there already is in as if she falls she will rupture her abdomen. Definately put a shallow water bowl in so she can drink. DO NOT use a tarantula sponge or beetle jelly.
