I'm no expert, but I think a lot of people say they don't want people crossbreeding or every breeding related fish. Which is half good half bad. It's bad because yeah you could over breed a family or such and end up getting bad effects. However, people seem to forget a lot of wild fish are related if they live near one another, being of the same species that is. Mutations and other oddities in the wild that would ensure the end of a species could look very cool in a home aquarium with little to no harmful effects.
Take for instance one of my favorite fish the Pleco.
Let's say a pleco species has an odd mutation and it grows horns but maybe the horns are more like tusks and however they form they form in a way that the fish in the wild can't eat, because of the tusks being in the way for the size of their natural food. However this would be taken care of by feeding it a different food in a home aquarium and having a nice mutation that maybe it passes on to its offspring.
My personal view, again I'm no expert on the matter and I may even be wrong but, I think anyone who's saying it's bad to cross or interbreed are just big fish farm people who don't want people breeding their own fish or don't want a wider variety then there already is. that's just me boredly rambling on though so pay it no mind.
