My son has a rose hair tarantula for almost a whole year now. She is NEVER taken out of her tank but we keep water and food for her at all times. I read about tarantula's molting but have yet to see her do it. Is that because she is already grown and doesn't need to or maybe I don't have the proper environment for her to molt? She stopped eating her crickets so I took the other two out and left her for almost two weeks without food but she never did any molting. I fed her again and she ate two crickets right away. Any suggestions??
