I've had my female G. rosea for over 13 years. She was molting only once every 3 years when I first got her. So I am assuming she was at least 10 years old when I got her. She now hasn't molted in almost 5 years. She just started showing the same symptoms as the dehydrated tarantulas you see in the youtube videos. Her legs are in a constant curl , her abdomen is not shriveld, but feels very different then the normal soft fuzziness it has always felt like. Is she dingy of old age? It can't be dehydration, I've always cared for her properly. In the last year, she has barley been eating.
