Hybrids among the same genre of a fish rarely have any deformities, such as if someone was to cross a whole bunch of different Aulonocara's. That's pretty much how all new colors of fish are made. By doing this you are simply expanding the sifferent kinds of fish in the world, note that many types of Aulonocara's live in the same territory so crosses would have most likely happened in the wild. Even species that are declared their own species now were once considered a hybridization, that had no deformities.
