Hmmm, so what happens in nature? In the native habitat of the fish, unless
you are suggesting that there is absolutely no cross breeding in natural

Species that may cross usually don't live in the same area. They never
see one another until they meet in an aquarium. Even the common
aquarium hybrids such as those that occur in lake Malawi species never
meet in nature. The collectors are not allowed to dump excess fish
back into the lake. If they did some hybrids would occur. It's the
artificially forced cohabitation of different species from different
areas that produces the occasional cross.

It is very, very, very rare for hybrids to occur in nature.
