I agree in part that breeders should take care that the hobby is maintained or strengthened by making sure excessive inbreeding is prevented, inasmuch that the overall genetic strength of the domestic strains are able to withstand disease and are healthy. Mollys, platys, and swordtails had this problem in the past (and maybe still do today, not sure). But my gripe is the bazillion names various sellers pull out of their hind-ends. Some org like the ACA, NADA, or whatever needs to sit down and at least set down some of the strains. And just because one stripe or a couple of dots don't express themselves in a couple of offspring, doesn't mean that that fish isn't a red checkerboard instead of a whatever. I think it sows confusion and allows for unscrupulous sellers to take advantage of beginners in the hobby, thereby affecting the growth of the hobby.
