I have one, and even after months of proper care, she still wobbles. :| I don't know why so many breeders act as if the wobble isn't an issue. When we changed my girl's substrate, it was ridiculous. She was flailing, arching every which way, ect. She's not the only rescue bp in this house, but she's the only spider rescue and the only one to have such a worrying reaction. Despite being rescued from similar conditions.
