I shouldn't have said that without the facts. It came from an earlier
discussion on this list that is missing some of the facts. I don't recall
the population, but a Phoenix pet store owner removed a genetically unique
population of Gambusia from a desert spring or stream some years back.
There is a written account of this in some publication, which I have read
myself but can't recall the source or species.

I think we can generally all agree that rare species which easy to rear in
aquaria, like livebearers and killies, and which are confined to limited
areas, would be collected to extinction if not protected.
