They were bred to be sterile. Like everything else in life, mutations,
forced or accidental, continue only in offspring. So if 1 fish in a
million is not sterile, it will breed and if they trait is dominant it
will be passed on to the offspring whether or not the other fish has it.
If it is recessive, it needs two parents with it.

Since fish breed in such large quantities, it does not take long for
them to find the right combination.

A perfect example of this is what was commonly known as the "brown ditch
fish"
in Thailand. Occasionaly one would be born with a purple color. About 30
years
ago, one person decided to find the purple ones and breed them. Now you
can
buy them in any store, sold by their latin name Betta Splendins.

This is a perfect example of evolution, but it is important to note that
the purple fancy tailed Bettas, are still considered the same species
as their dull brown short tailed ancestors.
