I have a Avicularia (Pink Toe) and a few weeks ago, (2 and a half) she totally enclosed her self in. I have a few decorative things in her cage that she likes to hangout in or climb on, since she is arboreal. Anyways, she hasn't been wanting to eat for those two weeks. I check on her everyday and yesterday she was totally fine, today i found her on her back as if shes about to molt. a hour later i find her not on her back and there isn't a old shell. I'm not sure what is going on with her. This is my first time having a arboreal tarantula, and also my first time ever experiencing this. Help anyone! I'm really interested in figuring out exactly what she is up to.
