Well, I am thinking a 30 Long or a 40 Breeder. Young Females, will not kill each other, so after breeding, and hatching, and then surviving, the left overs would be transferred there, then males plucked out when maturing and developing color, or you see an uptake in aggression. Young Females would be a better transition I believe. Older ones may be harder. In a 30 Long I could keep 15-20 maybe. Interesting topic for a later time, when I win the Lotto...lol!
