I got three Harpactira pulchripes as slings about two years ago. It turned out to be one male and two females. The male matured about two weeks ago and I'm thinking of to breeding them. I suppose they are sack-mates, but I don't know for sure. I would love to send the male to someone who has a female not related to the ones I have, but that is a difficult task. Should I not even try to breed them because they are, most likely, sack-mates?
