Actually, there are three livebearers, you also have Gambusia marshi
which is a pretty yellowish fish with purple hues in sunlight and a
prominant black midlateral band, they are pretty nasty to any other fish
too. The other is Xiphophorus gordoni which is a platy. Overall it is
a pretty grey looking fish. I've never seen longispinis, ever when I was
there for a week, they are pretty secretive. I do presently keep the
other two species from aquarium stock I aquired at the NYPENN council
meeting in Erie PA where the RSG had a get together at.
Thanks again
