The problem is that there is no evidence that they should and there is no
evidence that they shouldn't ;-)
While this happy state of blissful ignorance continues all sorts of
exotic species (including PNG species ) are being smuggled into this
country by various people using various methods for various motives and in
so doing are circumventing the protective quarantine barrier.
Sooner or later there will be a disease disaster from all this. In my
opinion this does pose some sort of threat but it is really not specific to
rainbows.
Last time we did this thread to death Peter you were going to try to get
some external viewpoints on threats from schooling fishes such as Rainbows
as well as some input from perhaps an evolutionary geneticist or two to see
how they felt about the basic mechanisms of mate selection in the wild and
how this affected the likelihood of hybridisation. Did you get any info one
way
or the other ?
