As you go farther and farther down a strain u do run across complications such as deformation, sterlity, and essentially fish that arnt too hardy. I have been extreamly lucky so far, but i will be adding a new stain after the fourth generation as i do not wish to ruin the whole project. Its just a matter of coming up with the right strain to add to mine, i did some serious hunting from one fish store to another to find the grandparents, but aquabid looks to be the easiest way to go about it
