I've had a mature male attempt a post-ultimate molt just 4 months after his ultimate molt with only eating 2 or 3 times. Some males just live longer than other males.It's just like powerfeeding a younger tarantula--once they "fill up" they stop eating and go into premolt.
Haplopelma lividum mature males can be expected to live for a year or less. A "few" years would be an abnormally long time for one to live.Binky/Carol said:He will only live for a few years.
