reading up i read that its "stressed" if the spider is curled up "hiding" she (my t) has this stance all the time.. she goes tighter if i am in there cleaning poop or bump her when i am maintaining her cage. so i assume that it is normal... posted in another forum and they just talked about how my aquarium wasn't right and didnt answer the question. (also got her a proper one with front vents today) the second pic is her old aquarium.. the 3rd pic (with tape measurer) is her when she is balled up tight tight (clearly stressed) the 4th is her new aquarium. had her in the old one for 3 weeks and only had her for 3 as well.. just wanna make sure she isnt stressed (assuming she)
