Female tarantulas don't die after producing an eggsac, in fact they can produce a dozen or more eggsacs in a lifetime. Your tarantula can get 20 or 30 years old. Males don't die after mating either - males of that species can last several years after maturing.
Nice t, that a mexican red knee?
As stated above, mating and producing an egg sack does not affect their life span, females can live up to about 30 years, males about 10 if im not mistaken? someone correct me if im wrong on the males.
Ditto the above. @Apestabrook I think 10 is the max for males. I seem to have a lot of issues finding approximate life span for this species. A lot of sources list them as 3-5 years, but that seems really short for a Brachypelma species.
