Hi, I am not new to tarantula keeping however I am having issues with two Rosies that I take care of (I work at a small zoo). The keepers who previously took care of them were not feeding properly and were consistently removing webbing everyday. I have been there almost 4 months and these girls have not eaten nor molted. Nobody can even tell me the last time that they did. They are also very agitated tarantulas and are very defensive. My question is what should I be doing to help them?
