dont get me wrong here, i love to see multi pairs breeding and what not. but is the goal here to get the older broods to pair off and breed their own? all from the same original parents??? just not sure if thats such a great idea.
line breeding is ok but not so good if you exhaust the gene pool, most fish these days are so inbred, its wacked aye, look at yellow labido's most are awful looking, what a hobbyist / breeder should do is try to obtain a new partner from a different colony from time to time to replenish the gene pool , so theres a diverse in population, but i do agree with you RiftLakeRosco, take care..
