Advertisement I am new to tarantula keeping and just recently acquired my first. It is a Curly Hair tarantula of unknown age/gender, about 3.5 inches. It is noticeably laid back and eating young hissing cockroaches regularly, every 3-4 days. However, I have noticed a distinct lack of carcasses within its tank. I have seen it grab and bite them, but it usually retreats into its hide after that. Should I be concerned?
