The anecdotal recollection of Les Kaufman about the hybrid offspring
preferring their own company rather than that of either parent is
interesting. Of course they were ONLY CICHLIDS but it does in a small way
support the contention that accidental hybrids in the wild may not
necessarily lead to wholesale "deterioration in the genetic purity" of our
existing stocks in our streams as some of our well-known pundits would have
us believe.

There is a good little debate going on on cichlid-l on the hybrid topic.
I will try and cross post items between each list that seem important.

Dear George,

Many years ago we had an accidental hybridization of male M.
auratus x female L. fuelleborni. It produced what appeared to be a normal
clutch of young, with broken-stripe patterns. The young matured and
appeared to be entirely fertile, though this was not measured...there were
in any event many clutches. One was saved and reared, and students worked
with them to see if there was evidence for assortive behavior. There was.
The hybrids liked to be amongst themselves, and not with either parent
species. That's all. Not very formal.

We are now setting up hybridization trials with Lake Vic haps as
part of our genetic studies.
