Re: NANFA-- Interactions between Gambusia, Heterandia and

Thanks for your comments, Mike.

I am always tempted to try Gambusia in a community tank with
other species from the same area. It just so that I can personally
observe how aggressive they are, if at all. Perhaps some other time.

The livebearer tank has Hets and Mollies and they get along fine.
But, the Hets seem to be outcompeting or breeding faster than
the Mollies. I do have a male fish with a jet-black underside
which is quite small and looks like a cross between the two species.
It may just be a stunted, color-variation of the Molly.

It's good to know about J. floridae. I haven't kept any in years.
But, they are very pretty fish and I should get some again. When
I have an outdoor pond going later this summer, I'll obtain some
from the pet shop and pop them in the pond. I was originally
thinking of C. varigetus for the pond. We'll see ...

I recently finished up a collecting trip in the SE US. I can't give any

tested info, but these are the general patterns I saw during this trip

- -found Gambusia and Mollies coexisting in generally high abundance
and in close proximity (along with flagfish).
- -Gambusia seemed to dominate when coexisting with Heterandia, and
- I did not find Mollies and Heterandia coexisting (again,
only one week's worth of observations). Perhaps the young mollies would

outcompete Heterandia for food etc.
