I have looked in Freshwater creek - have you?
And I can tell you I didn't find a pristine undegraded waterway. and I
didn't find any SplendidaxTri hybrids but i did find some exotics - both
livebearers and Cichlids
Were the hybrids you are chortling about different sizes and maturities
indicating an ongoing population? How many specimens of these Hybrids were
there? How close were they to the Army camp? The info is hardly conclusive
and certainly wouldn't be acceptable to
<<Sure, tris are a native species, not a PNG one,
but it could have been a herbie or parkinsoni for all intense purposes.>>
Yes and they could have been Piranhas and Channas too, or perhaps Candiru
or whatever your fevered imagination can dream up to support your case ;-)
Next thing Peter will have us believe that no-one should keep trifasciatas
because of this extremely significant anecdotal case that only has to be
"fully documented from the available in formation" ;-)
No! It's not good enough for me ;-) And it shouldn't be good enough for you
either if you really wanted to consoder the "big picture" for a moment
instead of jumping in both feet in your "devil's advocate" jumpsuit ;-)
