Advertisement Hm... I think this means that of the two I collected when mating the female died.. (And was ripped completely in half) Do you think I need one more female to begin breeding with a nice gene pool because the males will die off quicker? Someone told me that four females and two males were a nice gene pool to start breeding for tarantulas. I was thinking about that (different species), but they look identical so I haven't put much thought into it. That last female is very aggressive and wouldn't let males or females in with her. Should I put them in a bigger terrarium to try and mate them? Anyways, thank you! I'm almost there. Edit: Do females usually consume their mates and/or do males die soon after mating?
