Are rosy reds native whereever the pond is? Wouldn't want to introduce
them into the ecosystem. But then gambusia might not the natiuve
either.

Gambies aren't native to most of north america, their native territories are
around the gulf of mexico. But the vector control districts don't have a
problem with introducing them to any body of water, even though in
hindsight, it might have not always been the wisest idea.

Out in northern california, they'll just dump a bucket full of them into the
flooded rice fields, especially after people started getting west nile.
